Résumé :
This study is a third-year (34 months) follow-up investigation of the socioemotional behaviours of preterm and fullterm children previously seen at four points in time during the first two years of life. A total of 42 mother/ child pairs were seen for videotaped mother/child and child/peer play sessions. The tapes were coded on a second-to-second basis using Izard's MAX facial affect coding system and a vocal affect coding system. Data analysis focused on the contribution of the individual difference variables of gender, birth status, attachment classification, and maternal contingency behaviour, to children's expressive development. Expressive patterns in the third year were also compared with those obtained during the children's second year. Results indicated that contrary to developmental theory, facial expressivity does not decrease, at least during this developmental period, and moreover, that vocal affective expression increases. It is suggested that what children learn in development, is greater flexibility in the use of different systems to communicate affect, and greater facility in modulating expressivity according to context. Birth status was found to continue to affect the nature of affective development into the third year; preterm children were less vocally expressive than their fullterm counterparts, and preterm females showed greater facial negativity. Few other gender differences in expressivity were apparent, although mothers treated their children differentially. Moderate maternal contingency in infancy was related to greater vocal affectivity in children. Insecure attachment was associated with a degree of apparent tension and affective disharmony.

Résumé :
Abstract Limited expressivity of emotion is one of the most common symptoms of major depression, particularly in older adults. Although assessing facial and vocal expressivity is very important for accurate clinical evaluation of geriatric depression, research has rarely examined older adults via telehealth technology. This study aims to quantify facial and vocal expressivity via a multimodal affective system with deep learning. A total of 19 Korean adults aged over 65 years with severe depressive symptoms participated in this research. Using smartphone video recording, 1,429 facial and vocal data were collected between July and December 2020. Recorded videos were transmitted automatically to the cloud system. Basic facial movements were extracted using combined video frames and mel spectrogram images. Compared to the AI hub of Korean images from big data, mood status was classified into seven categories (anger, disgust, fear, happiness, neutrality, sadness, and surprise). Frequencies of each mood were coded into continuous variables for each participant in each recording. When comparing video and text prediction to determine “true labels,” the overall accuracy was 0.69, with F1 scores ranging from 0.57 to 0.79. In addition, the most common emotions were angry, happy, neutral, sad, and surprised. This study suggests that smartphone-recorded video could function as a useful tool for quantifying mood expressivity. This study established a preliminary method of affective assessment for older adults for telecare use based on socially assistive technology at a distance from the clinic.

Résumé :
Background Machine learning–based facial and vocal measurements have demonstrated relationships with schizophrenia diagnosis and severity. Demonstrating utility and validity of remote and automated assessments conducted outside of controlled experimental or clinical settings can facilitate scaling such measurement tools to aid in risk assessment and tracking of treatment response in populations that are difficult to engage. Objective This study aimed to determine the accuracy of machine learning–based facial and vocal measurements acquired through automated assessments conducted remotely through smartphones. Methods Measurements of facial and vocal characteristics including facial expressivity, vocal acoustics, and speech prevalence were assessed in 20 patients with schizophrenia over the course of 2 weeks in response to two classes of prompts previously utilized in experimental laboratory assessments: evoked prompts, where subjects are guided to produce specific facial expressions and speech; and spontaneous prompts, where subjects are presented stimuli in the form of emotionally evocative imagery and asked to freely respond. Facial and vocal measurements were assessed in relation to schizophrenia symptom severity using the Positive and Negative Syndrome Scale. Results Vocal markers including speech prevalence, vocal jitter, fundamental frequency, and vocal intensity demonstrated specificity as markers of negative symptom severity, while measurement of facial expressivity demonstrated itself as a robust marker of overall schizophrenia symptom severity. Conclusions Established facial and vocal measurements, collected remotely in schizophrenia patients via smartphones in response to automated task prompts, demonstrated accuracy as markers of schizophrenia symptom severity. Clinical implications are discussed.

In the opera Sing the Body Electric! A Corporatorio, artists from the disciplines of opera, dance and the development of new musical instruments collaborated to create an onstage fusion of different technologies and artistic practices that connected performer, scenography and instrument. Gestures and movements of singers were captured by custom-built technologies. The singers also used custom-built technologies for transforming their vocal qualities and for creating synthesized accompaniment in real time. In this way the singers’ bodily musical processes further extended their vocal performances, rooted in operatic praxis, allowing for heightened expressivity and emergent scenic subjects.

Résumé :
The article examines the genres of the vocal and the choral symphony in connection with the author’s vocal symphony Finland for soprano, tenor and orchestra set to Evgeny Baratynsky’s poem with the same title. It also discusses the issue of expression of the literary text in vocal music, as viewed by a number of influential 19th and 20th century composers, music theorists and artists. Among the greatest examples of the vocal symphony are Gustav Mahler’s Das Lied von der Erde and Alexander von Zemlinsky’s Lyrische Symphonie. These works combine in an organic way the features of the symphony and the song cycle. The genre of the choral symphony started with Beethoven’s Ninth Symphony and includes such works as Mendelssohn’s Second Symphony, Scriabin’s First Symphony and Mahler’s Second, Third and Eighth Symphonies. Both genres exemplify composers’ attempts to combine the most substantial genre of instrumental music embodying the composers’ philosophical worldviews with that of vocal music, which expresses the emotional content of the literary texts set to music. The issue of expressivity in music is further elaborated in examinations of various composers’ approaches to it. Wagner claimed that the purpose of music was to express the composers’ emotional experience and especially the literary texts set to music. Stravinsky expressed the view that music in its very essence is not meant to express emotions. He called for an emotionally detached approach to music and especially to text settings in vocal music. Schoenberg pointed towards a more introversive and abstract approach to musical expression and text setting in vocal music, renouncing outward depiction for the sake of inner expression. Similar attitudes to this position were held by painter Wassily Kandinsky and music theorist Theodor Adorno. The author views Schoenberg’s approach to be the most viable for 20th and early 21st century music.

Résumé :
The article discusses the relationships between musical performance, theatrical space and gesturality in Christoph Marthaler’s operatic productions. The stage design, the types of actor’s physical and vocal expressivity in “Le Nozze di Figaro”, “La Grande Duchesse de Gérolstein”, “Kát’a Kabanová”, “Věc Makropulos”, “Les Contes d’Hoffmann” and “Tristan und Isolde” are studied. Gesture, vocalisation and text in Marthaler’s productions are discussed and interpreted by considering the mismatching of dance and musical rhythm, the contrast of academical and non-academical singing manners or soundless articulation, as well as emphasizing the visual side of musical performance. Ensemble music-making and figurative gestures are the metaphors of power relations, total control and the collapse of social structures. It is concluded that the ways of vocalization and the types of gestures embody the system of power. The society in Marthaler’s operatic stage productions appears as an ensemble of the discursive practices.

Résumé :
The article presents the results of the cyclical organization of Pierre Boulez’s Le Marteau sans maître in the aspect of combining the principles of linear and non-linear organization. The composer created a work of a probabilistic type, in which dispersed and localized sub-cycles coexist with each other. Their core is formed by the vocal movements in which René Char’s poems are interpreted. The number of compositional units in these structural-thematic groups coincides with the quantitative factor of the segments of the composition’s main series. The embedding of sub-cycles homogenous in their content into a linear set is analogous to the procedure of interpolation. In the dispersed sub-cycles Char’s title poem stipulates the system of expressive means which is replicated in all the movements at various levels of fullness, but always in recognizable ways. In the localized structural-thematic groups the wholeness is formed in the process of ascertainment of the substantial images and the common elements of musical expressivity in the movements pertaining to various sub-cycles. Here the vocal movement becomes the “point of convergence” which brings to light the coincidences and activates the additional semantic overtones present in the poem. In his Le Marteau sans maîtreBoulez demonstrated the possibilities of compositional variability in the conditions of the system of cycles created by them presuming the simultaneous activity of the linear and non-linear organization with various types of connection.

Résumé :
Objectives: Mindfulness has been explored in the clinical and educational fields but has rarely been studied in the music domain. This study investigated the effects of teaching eight-week Mindfulness for Singers courses on vocalists’ music education and performance. Methods: A mixed methods approach was utilized, which included controlled and randomized controlled trials using standardized and novel mindfulness measures pre- and post-intervention, interviews post-intervention and three months later, concurrent diaries, and a blinded teacher study. Participants included singing students (total n=52) and their teachers ( n=11) from a university and a music college over a period of two years. Results: Levels of mindfulness increased over the intervention for experimental participants in comparison to controls. Considering their total student cohort, teachers identified 61% of eligible mindfulness singing participants as having completed the mindfulness intervention. Experimental participants reported that learning mindfulness had positive effects in lessons, solo and group instrumental practices, and when performing on stage. They described more focus and attention, positive effects of increased body awareness on singing technique, enhanced socio-collaborative relationships, reductions in performance anxiety, and beneficial effects whilst performing, such as more expressivity and enjoyment. Conclusions: Learning mindfulness had positive holistic effects on vocal students and was well received by their mindfulness-naïve singing teachers. Findings suggest that it would be highly beneficial for mindfulness to be made available in music conservatoires and university music departments alongside singing lessons for singers to enhance their present experience as vocal students and their futures as performers and teachers.

AbstractThis essay reconsiders the constituencies of fans and detractors present at prime and bursting 1970s dicsos. It argues for a more gender-inclusive conception of discos multiracial ‘gay’ revellers and for a particular convoluted conception of ‘homophobia’ as this applies to the Middle-American youths who raged against disco in midsummer 1979. Their historic eruption at Chicago’s Comiskey Park came just weeks after the chart reign of Gloria Gaynor’s ‘I Will Survive’, today a classic emblem of gay culture in the post-Stonewall and AIDS eras and arguably disco’s greatest anthem. Disco inspired lovers and haters, too, among music critics. Critical adulation and vitriol are conjoined in the present reading of musical rhetoric, which explores disco’s celebrated power to induce rapture in devotees at the social margins while granting anti-disco critics’ charge of inexpressivity in its vocals. In ‘Survive’ musical expressivity is relocated in the high-production instrumentals, where troping of learned and vernacular, European and Pan-American, sacred and profane timbres and idioms defines a euphoric space of difference and transcendence. The use of minor mode for triumphant purposes is also a striking marker of difference in ‘Survive’ and is among the factors at work in the song’s prodigious afterlife.

Résumé :
Ch.-M. Widor (1844–1937) inscribed his name in the history of French music primarily as an author of organ works (10 Organ Symphonies, 1872–1900, in particular). But other genre branches of his creativity (symphonic, chamber-instrumental, chamber-vocal, operatic, choral) remains less famous for wide public. This quite vast layer is mostly not studied in musical science. However, at the recent time the interest is somewhat growing both among musicologists (A. Thomson, E. Krivitskaya, M. R. Bundy), and among the performers, which confi rms the relevance of this article. The objectives of this study are to consider compositions by Ch.-M. Widor (Piano Concerto No.1, Fantasy, Piano Concerto No.2) both in terms of features of individual creator style and context of concert branch history in France. Information about works is supplemented by the analysis of the basic musical text parameters. Ch.-M. Widor graduated the Brussels Conservatory, where he was studied from 1859 to 1863 – in classes of organ (J.-N. Lemmens) and composition (F.-J. Fetis). At 1860s, the young man was visiting Paris. Soon he was acquainted with C. Saint-Saens, which infl uenced Ch.-M. Widor not only in terms of his executive career turn, but also was etalon of instrumental writing. It seems that the writing of instrumental Concertos for violin (ор. 26, 1877), cello (ор. 41, 1877), and piano (ор. 39, 1876) in many ways is owed by C.Saint-Saens and the impulse to French music of the 1870s given by him. Piano Concerto No.1 f-moll by Ch.-M.Widor was well appreciated by the contemporaries of the composer. In fi rst movement (Allegro con fuoco) the active narrative is combining with predominantly lyrical mood. It passes in constant pulsation without any whimsical tempo deviations, as well as without cadenza using. Contemplative and philosophical meditations are concentrated at the second movement (Andante religioso). The exposition of ideas is embodied in oppositions of characters, concentrated and depth in front of light and joyous. By the way, a little similar can be found in Andante sostenuto quasi adagio of Piano Concerto No.1 (published in 1875) by C. Saint-Saens. The cycle is crowned with a lively scherzo fi nal with elegant dotted rhythm using. On the whole we can say that the Piano Сoncerto No.1 by Ch.-M. Widor purposefully continues the traditions of C. Saint-Saens. This is noticeable in the clarity of the structure, emphatic melody, and also in some specifi c features – the avoidance of long-term solo cadenzas and the absence of expanded orchestra tutti’s, as well as the laconicism of development section at the fi rst movement. Echoes of F. Liszt and C. Franck can be heard in Fantasy As-dur op. 62 for piano and orchestra (1889, dedicated to I. Philipp). Ch.-M. Widor shows interest in this genre type as many other French authors at 1880–1890s. In work there are many counterpoint and variation elements, which is due to author’s mastery of organ-polifonic writing. In our opinion, eclectic combinations of the main subject in the spirit of F. Liszt – R. Wagner with oriental saucy theme at the end of composition are quite in the style of C. Saint-Saens. Piano Concerto No.2 c-moll (1905) is standing out with its clear attachment to the late-romantic line. It is somewhat out of the general context of genre existence in France, especially when comparing with signifi cantly more traditional Piano Concertos by B. Godard (No.2, 1894), C. Saint-Saens (No.5, 1896), T. Dubois (No.2, 1897), A. Gedalge (1899), J. Massenet (1902). This manifests itself in appeal to fateful gloomy spirit, abundance of dark paints in the sound, the complication of the tonal-harmonic language, increased expressivity, psychologization. Here are found more fi ne-tooth application of timbre orchestral potential (in comparison with the Piano Concerto No.1), as well as increasing of orchestra importance upon the whole. This is paradoxical, but its performing tradition has developed not in the best way, so that nowadays this remarkable work is very rarely heard at concert halls. In our time, the author’s creativity is a real terra incognita that encompasses a lot of hidden masterpieces. Results of the research bring to light that examined works by composer are outstanding illustrations of French romantic music. Ch.-M. Widor is an example of original talent that continues the late Romanticism line in France at the end of 19th and fi rst third of the 20th century, together with other authors – L. Vierne, V. d’Indy, A. Magnard, F. Schmitt. His works for piano and orchestra quite deserve to become on a par with recognized masterpieces, included in the concert repertoire of pianists and orchestras by different countries of the world. The perspectives of the further research are defi ned in more detailed analytical labors, including the extension of analysis over Violin Concerto op. 26 and Cello Concerto op. 41 by author. The learning of these works will allow to complement the history of the concert genre of French Romanticism with new details, that will enable to see the evidence of succession and the vitality of traditions.

Résumé :
Background. The modern science reconsiders various conceptions, which were influencing the theory and practice of musical art over the centuries. Particularly, there is much talk today about the fact that marking of female opera roles as “coloratura” according to the principle of their technical complexity and diapason wideness is quite nominal and not connected directly with singing voices’ gradation. Gradually entrenched tendency of denial of the female voice’s definition as “coloratura” has developed, and it is based on the argument that this characteristic reflects parameters of composer’s objectives rather than the voice’s nature. Probably, that’s why there are works in repertoire of certain female vocalists (for instance, Maria Callas and contemporary Canadian singer Natalie Choquette), which are usually performed by owners of “different” voices. However one cannot deny the fact that certain opera roles are composed specifically for coloratura soprano, despite the fact that indications of it are missing in manuscripts. N. Rimsky-Korsakov’s opera heritage is exponential in this connection; the destination of particular female roles for coloratura soprano is unquestionable – Snow Maiden, Marfa, Volkhova, Tsaritsa of Shemakha, etc. And though this roles are performed by female vocalists of various voices in today’s theatrical practice, it seems to us that voice’s characteristics have principal significant for appropriate implementation of author’s conception. Objectives. Thus, the purpose of the study is to identify the significance of the voice’s particularity factor as a carrier of a certain imagery in the composer’s conception and in the performer embodiments of opera parts (separated opera arias). Methods. The methodological basis of the study is the unity of scientific approaches, among which the most important is a functional one, associated with the analysis of the genre as a typical structure. Results. The Gogol’s plot became the basis of several operas, the most famous of which are “Cherevichki” (“The Little Shoes”) by P. Tchaikovsky and “Noch’ pered Rozhdestvom” (“Christmas Eve”) by N. Rimsky Korsakov. The comparison of this two works clearly shows the fundamental difference in composers’ conceptions. In P. Tchaikovsky’s interpretation the lyrical line is extracted from the literary primary source. But for N. Rimsky Korsakov the comparison of the real and fantastic world becomes the main thing in this opera. Therefore the role of Vakula is written quite schematically, but Oksana’s image is interesting developed, it is presented in progress – from carefree girl to loving woman. This progress is obvious when comparing Oksana’s Arias from Act I and Act IV. The Aria from Act I is a peculiar synthesis of national and Italian singing traditions, a prime example of entrance aria (di sortita), which presents the character’s portrayal and comprises such basic components as slow introduction and episodes demonstrating technical possibilities of the voice. Oriental intonations, which are specific for composer’s vocal works, coupled with coloraturas, give the impression that Oksana is “not from this world”. According to lots of researchers, the whole N. Rimsky Korsakov’s opera “metacycle” is an artistic integrity united by a generic idea that defined the unity of approach to implementing of “type” (including female) characters. The intonational canvas of every particular role (the choice of so-called intonational complexes – “a cold” or “a warm”) is determined by character’s affiliation with natural or fairy-tale locus. Oksana’s portrayal for N. Rimsky Korsakov has been ambivalent. On the one hand, she doesn’t relate to “another world” like Snow Maiden or Volkhova; on the other hand – Oksana is a fairy-tale character. Therefore composer uses partly the same strokes in the development of the portrayal as for female fairy-tale characters. However, the formation of this character’s personality is revealed through the transformation of “cold” (fairy-tail) intonational complex to “warm” (“alive”). Two performances of the first Oksana’s Aria are briefly reviewed as an example: the concert performance by Gohar Gasparyan, an Armenian lyrical coloratura soprano (1924–2007), and a recording from the Inessa Prosalovskaya’s CD “Arias from operas”, the Russian lyrical dramatic soprano (born in 1947). G. Gasparyan’s idea was to present the portrayal of a young girl of the people. Therefore the singer levels virtuosic components of music material as much as possible, and a coloring of her voice, for which it was easy to sing the second A sharp above middle C, emphasizes lyrical hints of Oksana’s Aria. Also the significant textual cuts becomes one of important parameters of creation of a “gentle” young girl’s portrayal; they not only transform the expanded aria into the form, which is close to a song in scale, but also significantly reduce specifically those snippets, in which technical difficulties are concentrated. Version by I. Prosalovskaya presents another interpretation, original sound of which is largely due to the singer’s timbre of voice. Its deepness, expressivity and completion absolutely modify personal characteristics of the N. Rimsky-Korsakov’s character. Therefore we observe not a young girl already, but a woman – passionate and confident. Thus, it could be concluded that timbre color’s specificity of the voice of female opera singer has a significant impact on features of the character that she embodies. It is obvious that this specificity determines all the parameters of the performer’s version of the composer’s work (both a separate aria and the opera as a whole). A more detailed study of the relationship between the voice timbre and the semantic and compositional decisions characterizing an individual performer style seems to us a promising direction for further research.

Résumé :
Choral method textbooks include various strategies on when and how to introduce expression in song acquisition including vocal modeling. In two previous studies, participants who learned expressive elements early in a song-learning sequence (infused-expression) performed those elements more accurately than those who learned them at the end of the sequence (post-expression). However, the infused-expression sequence had an expressive model throughout, whereas the post-expression sequence had an expressive model only at the beginning and end. The purpose of this study was to remove the modeling variance between sequences. Middle schoolers learned two songs with an expressive model throughout, using two different sequences (infused-expression and post-expression). We found no significant difference in expressive accuracy between sequences. When students learned a song with an expressive model, regardless of sequence, students sang with expression. Teachers should consider always modeling with expression regardless of whether or not the objective of the rehearsal is about expressive elements.

Objectives: Multiple machine learning-based visual and auditory digital markers have demonstrated associations between major depressive disorder (MDD) status and severity. The current study examines if such measurements can quantify response to antidepressant treatment (ADT) with selective serotonin reuptake inhibitors (SSRIs) and serotonin–norepinephrine uptake inhibitors (SNRIs).Methods: Visual and auditory markers were acquired through an automated smartphone task that measures facial, vocal, and head movement characteristics across 4 weeks of treatment (with time points at baseline, 2 weeks, and 4 weeks) on ADT (n = 18). MDD diagnosis was confirmed using the Mini-International Neuropsychiatric Interview (MINI), and the Montgomery–Åsberg Depression Rating Scale (MADRS) was collected concordantly to assess changes in MDD severity.Results: Patient responses to ADT demonstrated clinically and statistically significant changes in the MADRS [F(2, 34) = 51.62, p &lt; 0.0001]. Additionally, patients demonstrated significant increases in multiple digital markers including facial expressivity, head movement, and amount of speech. Finally, patients demonstrated significantly decreased frequency of fear and anger facial expressions.Conclusion: Digital markers associated with MDD demonstrate validity as measures of treatment response.

Résumé :
Abstract In electronic musical instruments (EMIs), the concept of “sound sculpting” was proposed by Mulder, in which imaginary objects are manually sculpted to produce sounds, although promising has had some limitations: driven by pure intuition, only the objects’ geometrical properties were mapped to sound, while effort—which is often regarded as a key factor of expressivity in music performance—was neglected. The aim of this paper is to enhance such digital interactions by accounting for the perceptual measure of effort that is conveyed through well-established gesture-sound links in the ecologically valid conditions of non-digital music performances. Thus, it reports on the systematic exploration of effort in Dhrupad vocal improvisation, in which singers are often observed to engage with melodic ideas by manipulating intangible, imaginary objects with their hands. The focus is devising formalized descriptions to infer the amount of effort that such interactions are perceived to require and classify gestures as interactions with elastic versus rigid objects, based on original multimodal data collected in India for the specific study. Results suggest that a good part of variance for both effort levels and gesture classes can be explained through a small set of statistically significant acoustic and movement features extracted from the raw data and lead to rejecting the null hypothesis that effort is unrelated to the musical context. This may have implications on how EMIs could benefit from effort as an intermediate mapping layer and naturally opens discussions on whether physiological data may offer a more intuitive measure of effort in wearable technologies.

Résumé :
Music composition is an art of courage and thoroughness. After nearly four years of playing jazz with Queen’s music professor Greg Runions (winner of the 2006-07 Queens Music Department Teaching Award) and studying music theory and analysis, I have recently delved into the fascinating art of writing original music in the broadly defined jazz idiom. The opportunity to give something back to the creative music community has been both humbling and inspiring. Through Prof. Runions impressive experience as a prolific local composer, I have learned about the challenges of connecting melodic ideas with music harmony that both pleases and challenges the listener. In two semesters of study, we have explored jazz arranging for a variety of instrument groups, the complex art of chord extensions and modulation, and writing melodies over chord progressions that are memorable and enjoyable. I have produced a dozen songs in lead sheet format, similar to the way music is found in jazz performance fake books. Some of these pieces have been fleshed out to cover a wide range of instrumental performance, including solo piano, jazz combo, vocal jazz ensemble, and full jazz ensemble. I plan to continue this process throughout my life as new inspiration and musical situations arise, seeking to grasp the expressivity and enjoyment that music instills in us all.

Résumé :
At the beginning of his recent collection of essays in queer studies, Jeffrey Escoffier makes the assertion at once portentous and banal that “the moment of acknowledging to oneself homosexual desires and feelings … and then licensing oneself to act ... is the central drama of the homosexual self.” That “moment of self-classification,” he explains, “is an emergency – sublime, horrible, wonderful – in the life of anyone who must confront it.” (1) In the theatre of my own biography, I am unsure how or when I first played out this epiphanic drama of queer self-acknowledgment, but I can vividly recall the first time someone else enacted it for me. In elementary school, at the age of ten, a fellow pupil cornered me in the school playground and announced with calculated precocity to anyone who cared to listen that I was, as he put it, “a homo.” Unlike some of my congregated peers whose chorus of “what’s a homo?” provoked a dizzying exchange of infantile misinformation, I was only too well aware of the term’s meaning and, shocked that my queerness should not only be revealed but also be so transparently legible that even a boorish bully might detect it, slid away in fearful embarrassment. What proved most unsettling to me, however, was that my nascent homosexuality should have been evidenced in this playground spectacle of queer exposure, not on the basis of same-sex desire but, rather, on that of passionate devotion to a woman. Earlier that day, our schoolteacher had directed us to write and then read aloud to the class a composition entitled, “My Hero.” Where most of my classmates wrote predictable tributes to normative role models of the time like Neil Armstrong, Greg Chappell, Muhammad Ali, and even Jesus Christ, I penned an effusive homage to, what I described in the essay as, that “radiant star of stage and screen, Miss Julie Andrews”. It was this profession of ardent affection for a female film star that led directly to my schoolyard outing. As my accuser put it when explicating the deductive rationale behind his sexual detection, “Only a homo would love Julie Andrews!” Even at age ten, the paradoxical (il)logic of this formulation was so glaring as to all but slap me hard across the face – an action transposed from the metaphoric to the literal by my playground adversary who, not content to let “the homo” escape too readily or lightly, pursued me across the schoolyard and pushed me face-first into the asphalt. How could my declaration of desire for a female star – which in strictly definitional terms should have seemed, if anything, eminently heterosexual – be taken so assuredly as a marker of homosexuality? Why and how could my loving Julie Andrews provoke such an explosive manifestation of juvenile homophobia? The answers to these questions were already known, if only intuitively and, thus, only partially, to the ten-year old me. Like many other elements of my childhood, my love for Julie Andrews formed part of what I was fast recognizing was an ever-expanding and ever-consolidating category of bad object-choices – a diverse array of cultural and social cathexes variously abjectified, proscribed or deemed otherwise inconsonant with dominant modes of sexual selfhood. Redefined as a symptom of sexual dissonance, my devotion to Andrews suddenly became a catalytic signifier of shame, a palpable marker of my failure to achieve heteronormality and, thus, another attachment to cache away in the cavernous closet of protogay childhood. That this scenario will sound instantly familiar to many is evidence of the extent to which a politics of shame is routinely mobilized – most potently, though by no means exclusively, in childhood – to stigmatize and thus discipline queer subjectivities. Much of the breathtaking success with which mainstream culture is able to install and mandate a heteronormative economy depends directly on its ability to foster a correlative economy of queer shame through which to disgrace and thus delegitimate all that falls outside the narrow purview of straight sexualities. Not that such processes of juridical stigmatization are necessarily successful. Shameful and shameless are, after all, but a suffix apart and a good deal of the productivity of queer cultures – as of queer lives – resides precisely in the extraordinary capacity they obtain for not only clinging stubbornly and defiantly to the outlawed objects of their desire but investing these objects with a near-inexhaustible source of vitalizing energy. The scene of my schoolyard shaming may have effected a public occlusion of my love for Julie Andrews, but it in no way quelled or attenuated that love. Indeed, transformed into a sign of my developing homosexuality, my attachment to Andrews became more than ever an integral component of my subjectivity and an indefatigable resource for survival in the face of what I perceived to be an unaccommodating social world. Eve Kosofsky Sedgwick dubs these survivalist dynamics of queer culture “reparative” in the sense given the term by object-relations theory as an affirmative impulse to repair or make good the losses of subjective constitution. Unlike the competing paranoid positionality which in object-relations theory is understood to fracture the world into colliding part-objects and is marked by “hatred, envy, and anxiety”, the reparative dynamic is marked by love and seeks to reassemble or repair the subject’s world into “something like a whole” that is “available both to be identified with and to offer one nourishment and comfort in turn.” (Sedgwick, 8) For Sedgwick, this idea of a reparative impulse speaks powerfully to the inventive and obstinate ways in which queer subjects negotiate spaces of self-affirmation in the face of a hostile environment, or as she evocatively puts it, the ways in which queer “selves and communities succeed in extracting sustenance from ... a culture whose avowed desire has often been not to sustain them.” (35) As a paradigmatic example of and governing trope for this reparative tradition of queer survivalism, Sedgwick offers, significantly for my purposes, the image of the proto-queer child or adolescent ardently (over)attached to a cultural text or object, passionately investing that text or object with almost talismanic properties to repair or make good a damaged socius . “Such a child,” she writes, “is reading for important news about herself, [even] without knowing what form that news will take; with only the patchiest familiarity with its codes; without, even, more than hungrily hypothesizing to what questions this news may proffer an answer.” (2-3) This characterization of a reparatively positioned proto-queer reader resonates profoundly with my own fiercely loving attachments to Julie Andrews. Much of the energy of these attachments – certainly in childhood and, perhaps less urgently but no less decisively, in adulthood – springs directly from the reparative performances to which this particular star has been cast in the playhouse of my own imaginary. To wit: a cherished ritual from childhood. In the days when I was growing up, the days before VCRs and cable television, my Andrews fandom was of necessity organized not so much around her film texts as around her recordings. While I had seen her films and these were vital, generative sites for my fan passions, the primary focus for those passions – where they were practised, indulged, nurtured – was her vocal recordings. On long, listless afternoons, returned home from school, I would rush to the living room, position myself firmly in front of the family hi-fi and blissfully listen my way through my expansive collection of Julie Andrews LPs. My favourite, without doubt, was the soundtrack recording for The Sound of Music, which I would play and replay for hours on end. I can still recall the palpable sense of breathless anticipation when, unsheathed from its cover and reverently placed on the turntable, the disc would crackle to life. A whispering breath of wind, an echo of birdsong, a rapid swell of violins, and Julie’s inimitable voice would break forth in fortissimo triumph, leaping through the speakers and enveloping the room with melodic abundance. To augment the sense of excitement, I would, while listening, gaze intently at the record cover with its celebrated image of Julie leaping in mid-flight like a preternatural oread, her skirt billowing up with carefree delight, arms swinging open in joyous welcome, effortlessly holding aloft a guitar case and a travelling bag, twin symbols of musical expressivity and liberating escape. Projecting myself into the scene, I would twirl with Julie in imaginary freedom, riding the crest of her crystalline voice in rapturous transport from the suburban mundanity of family, school, and straightness. Invested with the attentive love and astonishing creativity of juvenile fandom, Andrews provided not just the promissory vision of a life different from and infinitely freer than the one I knew, but the fantasmatic means through which to achieve and sustain this process of transcendence. If I loved Julie Andrews as a child it was because that love functioned as a process through which to resist and transfigure the oppressive banalities of the heteronormative everyday. Though unaware of it at the time, my childhood mobilization of a female star as a vehicle of, and for, quotidian transcendence has a long and rich pedigree in queer cultures, especially gay male cultures. From the enthusiasms of the nineteenth century dandies for operatic primi donne and the fervent gay cult followings in the mid-twentieth century of Hollywood stars such as Judy Garland and Bette Davis, to contemporary queer celebrations of dancefloor goddesses, diva worship has been a staple of gay male cultural production where it has sustained a spectacularly diverse array of insistently queer pleasures. While loath to generalize its heterogeneous functions and values, I submit that much of the enduring vitality of diva worship in gay male cultures resides in the commodious scope it affords for reparative cultural labour. Indeed, most critical discussions of gay diva worship posit in some fashion that gay men engage divas as imaginary figures of therapeutic empowerment. “At the very heart of gay diva worship”, opines Daniel Harris, is “the almost universal homosexual experience of ostracism and insecurity” and the desire to “elevate [one]self above [one’s] antagonistic surroundings.” (Harris, 10) Wayne Koestenbaum similarly claims that "gay culture has perfected the art of mimicking a diva – of pretending, inside, to be divine – to help the stigmatized self imagine it is received, believed, and adored." (Koestenbaum, 133) Tuned to the chord of reparative amelioration, diva worship emerges here as a vital practice of affective queer enfranchisement: the restoration of a functional selfhood and the provision of emotional resources through which to transcend – and survive – the often violent deformations of a heteronormative world. That such processes of male homosexual affirmation should be articulated through ardent devotion to a woman might seem a strange paradox. But just as love and sex are never inevitable correspondents, the presence of a heterosexual passion inscribed at the very heart of gay male culture by its long histories of diva worship is a sure – and welcome – sign of the irrepressible waywardness of desire and its stubborn refusal to fit the impoverished scripts that we nominate sexuality.
