Academic literature on the topic 'Vocal duets Analysis'

AbstractWe report on long-range duet interactions among twelve wild groups of lar gibbons (Hylobates lar) in Thailand. Statistical analysis demonstrates that groups were more likely to respond with an answering duet to a duet sung by a neighbouring group than to one sung by a non-neighbouring group in the population. A distinctive pattern of response among neighbours was to wait until a neighbouring group had finished its duet before immediately answering with a duet, resulting in avoidance of overlap between the two duets. Non-neighbours did not exhibit this pattern. The effect is shown to be due solely to neighbour status and not to the degree of mutual audibility of the duets. There was no evidence that, when duets overlapped, the first group to sing modified the length of its duet in response to the second duet, whether given by a neighbour or by a non-neighbour. In general, among those groups which responded to one another's duets, there were no identifiable leaders and followers: the order of duetting groups was random. We discuss why neighbours interact more by duet than do non-neighbours, and consider what may be the functions of avoiding overlap of duets.

Abstract Abstract. We provide the first detailed analysis of the vocal behavior of Pacific coast Plain Wrens (Thryothorus modestus modestus). Male Plain Wrens sing two categories of song phrase; one phrase is given as a solo song or duet introduction (I-phrases), while the other is sung primarily during duets (M-phrases). Females sing only one category of song phrase, usually during duets (F-phrases). Both sexes have repertoires of their respective song categories. Plain Wren duets show extreme temporal coordination: duets typically begin with male I-phrases, which are followed by the rapid alternation of female F-phrases and male M-phrases. These patterns are congruent with the solo and duet singing behavior of a sister taxon to the Plain Wren, the Canebrake Wren (Thryothorus modestus zeledoni). Our analyses of Plain Wren songs and duets reveal pronounced differences between males and females and contribute to our understanding of the complex duetting behavior of Thryothorus wrens.

Bird vocalizations might be used for specific recognition, territorial defense, and reproduction. Bioacoustic studies aim to understand the production, propagation and reception of acoustic signals, and they are an important component of research on animal behavior and evolution. In this study we analyzed the sound structure of duet vocalizations in pairs of Myiothlypis leucoblephara and evaluated whether the vocal variables differ among pairs and if there are differences in temporal characteristics and frequency of duets between pairs in forest edges vs. forest interior. Vocalizations were recorded from 17 bird pairs in three remnants of Atlantic Forest in southern Brazil. Six of the bird pairs were situated at the edge of the forest remnant, and 11 were in the interior of the remnant. The duets of different pairs between forest areas showed descriptive differences in the frequency, number of notes per call, and time between issuance of calls, with the main distinguishing feature being a change in frequency of a few notes in the second part of the musical phrase. The minimum frequency of vocalization was reduced at the private area than in the other two remnants (p <0.05). The duets of birds in the forest edge and forest interior did not significantly differ in minimum or maximum frequency of phrases (p> 0.05), phrase duration (p> 0.05) or number of notes per phrase (p> 0.05). Myiothlypis leucoblephara did not show a specific pattern with respect to issue of phrases in duets, but instead showed five different patterns, which were variable among pairs. There was a sharp decline or alternation in frequency between notes in the second part of the musical phrase for recognition among pairs. Variation in vocalization among M. leucoblephara duets may play a role in pair recognition.

Long-range vocal communication in socially monogamous titi monkeys is mediated by the production of loud, advertising calls in the form of solos, duets, and choruses. We conducted a power spectral analysis of duets and choruses (simply “duets” hereafter) followed by linear discriminant analysis using three acoustic parameters—dominant frequency of the combined signal, duet sequence duration, and pant call rate—comparing the coordinated vocalizations recorded from 36 family groups at 18 sites in Bolivia, Peru and Ecuador. Our analysis identified four distinct duetting patterns: (1) a donacophilus pattern, sensu stricto, characteristic of P. donacophilus, P. pallescens, P. olallae, and P. modestus; (2) a moloch pattern comprising P. discolor, P. toppini, P. aureipalatii, and P. urubambensis; (3) a torquatus pattern exemplified by the duet of Cheracebus lucifer; and (4) the distinctive duet of P. oenanthe, a putative member of the donacophilus group, which is characterized by a mix of broadband and narrowband syllables, many of which are unique to this species. We also document a sex-related difference in the bellow-pant phrase combination among the three taxa sampled from the moloch lineage. Our data reveal a presumptive taxonomic incoherence illustrated by the distinctive loud calls of both P. urubambensis and P. oenanthe within the donacophilus lineage, sensu largo. The results are discussed in light of recent reassessments of the callicebine phylogeny, based on a suite of genetic studies, and the potential contribution of environmental influences, including habitat acoustics and social learning. A better knowledge of callicebine loud calls may also impact the conservation of critically endangered populations, such as the vocally distinctive Peruvian endemic, the San Martin titi, P. oenanthe.

Many groups of animals defend shared resources with coordinated signals. The best-studied of these signals are the vocal duets produced by mated pairs of birds. Duets are believed to be more common among tropical-breeding species, but a comprehensive test of this hypothesis is lacking, and the mechanisms that generate latitudinal patterns in duetting are not known. We used a stratified sample of 372 songbird species to conduct the first broad-scale, phylogenetically explicit analysis of duet evolution. We found that duetting evolves in association with the absence of migration, but not with sexual monochromatism or tropical breeding. We conclude that the evolution of migration exerts a major influence on the evolution of duetting. The perceived association between tropical breeding and duetting may be a by-product of the migration–duetting relationship. Migration reduces the average duration of partnerships, potentially reducing the benefits of cooperative behaviour, including duetting. Ultimately, the evolution of coordinated resource-defence signals in songbirds may be driven by ecological conditions that favour sedentary lifestyles and social stability.

AbstractA new species of tyrant flycatcher (Suiriri islerorum) is described from the cerrado region of Brazil and adjacent eastern Bolivia. The species previously had been confused with Suiriri suiriri affinis, with which it is syntopic at multiple sites. The new species was first identified by voice. Although cryptically similar to S. s. affinis in many respects, the new species is readily identified by all vocalizations, bill size, color pattern of the tail, and shape of the central rectrices. Most distinctive are the male–female duets, which are accompanied by dramatic wing-lifting displays not performed by any congeners. Reciprocal playback experiments of tape-recorded vocalizations demonstrated that the new species and S. s. affinis do not respond to one another's vocalizations. We provide information on the natural history of the new flycatcher, along with spectrograms of its various vocalizations. We also provide vocal analysis of all other named taxa in Suiriri, and discuss the various intrageneric relationships. In particular, S. s. affinis and S. s. bahiae, although distinct morphologically, are vocally and behaviorally similar, and respond to one another's vocalizations in playback experiments.

Background. In 2018, the 170th anniversary of the death of Gaetano Donizetti (1797–1848) was commemorated. G. Donizetti created 74 operas of various genres and themes. He was the head of the Italian opera school in the second half of the 1830s, picking up the baton from G. Rossini and V. Bellini and anticipating G. Verdi’s searching. Having an apparent melodic gift, excellent skills of composing, knowledge of musical theatre, he created his works extremely quickly and easily – up to 3–4 operas per year, which caused repeated critical attacks. Opera works by G. Donizetti got a hard futurity. This music laid hold of audience in the 1830s–40s, but practically got out of the repertoire by the end of the 19th century, giving way to the masterpieces by G. Verdi and R. Wagner. Its revival began in the 50s of the 20th century, thanks to remarkable interpretations of great performers, in particular Maria Callas, Joan Alston Sutherland, Montserrat Caballé (since 1965), and others. A new success of opera masterpieces arose due to the fact that performing concepts restored the original author’s conception. Among the researchers and listeners, G. Donizetti’s operatic works eclipsed other spheres of his creativity, such as instrumental and chamber vocal music. But at the same time, G. Donizetti lived in the times of the widespread distribution of the romance, and the rapid growth of its popularity in the amateur and professional performing environment. He was an outstanding expert of vocal music and could not ignore this genre. Naturally there is a need for a more attentive approach to such a little-studied topic, as the composer’s chamber vocal music. Objectives. Gaetano Donizetti’s chamber-vocal creativity is the object of this study. The subject is the song cycle “Summer Nights in Posillipo” (“Nuits d’été à Pausilippe”) in terms of individual composer style. The objectives of offered article are not so much fi ll existing gaps on this issue, as taking a closer look at the romance genre, which is eclipsed by the composer’s opera compositions. The author of this work uses classical methods of analysis of historical and theoretical musicology. Results. Studies on the composer style of G. Donizetti in the Russian and Ukrainian languages are very limited in both quantitative and thematic terms. Most sources, including in other languages, consider opera works by the composer. The exact number of Donizetti’s romances is still unknown (from 250 to 270). The song cycle “Nuits d’été à Pausilippe” / “Summer Nights in Posillipo” (1836), consisting of 12 songs, is also not considered in the scientifi c literature. Typical for the fi rst third of the 19th century is the chronotope of this cycle, in which the poetics of the geographical toponym and the symbolism of the night are combined. Posillipo is a distinctive place in the northern part of the Gulf of Naples, with its unusually picturesque landscape and artifacts of ancient culture. The name of the song collection by G. Donizetti corresponds to the popular literature formula of the 1830s – “Florentine Nights” (1833) by H. Heine, “Egyptian Nights” (1835) by A. S. Pushkin, and others, in which the genre of the “night” novelistic cycle embodied. The musical implementations are “Night Pieces” op. 23 (1839) by R. Schumann, song cycle “Summer Nights” op. 7 (1841) by G. Berlioz, which were created in the period of composition writing (1836) by G. Donizetti. The novella-like character of “Summer Nights in Posillipo” is represented by incompleteness of lyric utterance, free alternation of fragments within the boundaries of a given topic, the variability of timbre solutions, varied choice of authors of poetic texts. Six solo numbers (Nos. 1–6) are supplemented by six duets for various timbre sets (Nos. 7–12, for 2 sopranos, soprano and mezzo-soprano, soprano and tenor, tenor and bass). The poems by four poets of Romanticism are involved: Leopoldo Tarantini (Nos. 1, 8, 10, 12), Carlo Guaita (No. 2), Michele Palazzolo (Nos. 7, 11), Francesco Puoti (No. 9), Victor Hugo (No. 6). Also the poems of the anonymous poet (No. 3) and the folklore text (No. 5) are used here. The cycle is “multilingual”, the Italian language coexists with the Neapolitan and French. The love theme prevails. We can talk about creation of a poetic-collective image entitled Homo amore. Solo songs (Nos. 1–6) form conditional self-contained cycle, which is distinguished by genre diversity. This is evidenced by both the designations of the composer himself (Barcarolle – No. 1, Romance – No. 2, Arietta – No. 3, Ballade – No. 4, Neapolitan song – No. 5), and signs of other genres (opera monologue – No. 1, Chivalric romance – No. 2, Serenade – No. 3, Alba – No. 6). The second little cycle is formed by the duets Nos. 7–12. The composer designates Nos. 7–11 as nocturne, while Nos. 12 as brindisi, or drinking song. G. Donizetti’s nocturnes are glad and lyrical, motile, virtuosic, theatrically spectacular. Life and earthly pleasures are glorifi ed in sounding. The atmosphere of a brilliant ball evening is felt here. The unifying factor in duets are the principles of the texture organization of vocal parts. The fi rst one is associated with the interaction of voices-parts with each other according to the principle of anti-phoning singing (Nos. 7, 9, 11). The second principle is associated with the simultaneous sounding of two voices (Nos. 8, 10, 12). The role of intonation relatedness at the songs is signifi cant. The thematism of twelve songs can be divided by the type of melodic core. As a result, there are three groups: I – themes Nos. 1, 2, 5, 8, 10; II – Nos. 3, 6; III – duets Nos. 7, 9. Conclusions. The applying of the “intonation vocabulary” of the epoch is refl ected in numerous allusions between the melodies of the romances by G. Donizetti and the works of his contemporaries (M. Glinka, F. Schubert) and successors (R. Hahn). The biggest interest is the composer work with the form. Acting within the framework of the repeatability (melodic and structural) and stanza form, G. Donizetti seeks to overcome this necessity in every possible way by various means. The structure of his romances “lives”, naturally unfolds in time, obeying the laws of vocal music. The results of “Summer Nights in Posillipo” analysis allow us to conclude about the originality of G. Donizetti’s creative decisions in the genre of romance.

Abstract Duetting, or the stereotypical, repeated and often coordinated vocalizations between 2 individuals arose independently multiple times in the Order Primates. Across primate species, there exists substantial variation in terms of timing, degree of overlap, and sex-specificity of duet contributions. There is increasing evidence that primates can modify the timing of their duet contributions relative to their partner, and this vocal flexibility may have been an important precursor to the evolution of human language. Here, we present the results of a fine-scale analysis of Gursky’s spectral tarsier Tarsius spectrumgurskyae duet phrases recorded in North Sulawesi, Indonesia. Specifically, we aimed to investigate individual-level variation in the female and male contributions to the duet, quantify individual- and pair-level differences in duet timing, and measure temporal precision of duetting individuals relative to their partner. We were able to classify female duet phrases to the correct individual with an 80% accuracy using support vector machines, whereas our classification accuracy for males was lower at 64%. Females were more variable than males in terms of timing between notes. All tarsier phrases exhibited some degree of overlap between callers, and tarsiers exhibited high temporal precision in their note output relative to their partners. We provide evidence that duetting tarsier individuals can modify their note output relative to their duetting partner, and these results support the idea that flexibility in vocal exchanges—a precursor to human language—evolved early in the primate lineage and long before the emergence of modern humans.

The paper is devoted to theproblematics of the late style in composer creativity. The typologies of the late style described in the musical science works of recent years (including the thesesby E. Nazaikinsky and N. Savitskaya) are systematized. The characteristic of B. Britten’s chamberheritage is given in the context of the achievements of the English composer’s school of аnew musical renaissance of the twentieth century. The purpose of the research is to reveal the specificity of the last opus phenomenon. Achieving the goal of the research involves using the following methods: genre approach, historical approach and stylistic approach. The specificity of the last opus phenomenon is revealed by the example of the Third String Quartet by B. Britten, which is recognized as the composer’s last opus. The late style of the composer is characterized in terms of orchestration, techniques, genre preferences and stylistic unity. Exposition of the main material of the study includes compositional and stylistic analysis of the Third String Quartet by B. Britten. In the paperheritage of B. Britten is considered as an example of a creative composer process which has an explicit division into several periods. The name of B. Britten is associated with the highest achievements of the English composer school of a new renaissance in the twentieth century. The researchers distinguish three periodsof B. Britten’s creativity. The first period is characterized by the interest in chamber music and various chamber compositions, the variation as a principle of development as well as the genre certainty. The individual style of the composer is formed in vocal musicearlier and more intensively. The second period is characterized by expressive orchestral writing, figurative concreteness and clarity of structures. The late period of B. Britten’s creativity is characterized by the desire to find the most flexible form of the modern performance. The stylistic synthesis reveals a reliance on ancient types and forms of playing music: Gregorian chant, heterophony, anemitonicpenta-tonic system and church modes. Most of his works are marked by the asceticism of expressive means. The scores are written in a stingy, honed manner, the composer uses instrumental compositions with vivid coloristic capabilities, but implements them with a subtle sense of proportion. The paper deals with the specifics of the B. Britten’s late style. According to the concept of N. Savitskaya the late style is the final evolutionary stage which includes stylistic elements of the early and mature stages of the composer’s creative formation in an in-depth and concentrated form. The researcher identifies the following types of late style: prognostic, consolidating and reduced. B. Britten’s late style can be classified as consolidating one. The paper isconcerned with the phenomenon of the last opus. B. Britten created three string quartets. The appearance of the first two was connected with the two hundred and fiftieth anniversary of the death of H. Purcell. The Third Quartet was written thirty years later, in 1975, in Venice, and was first performed after the death of B. Britten in 1976. This work was the last instrumental composition the authorcompleted. The structure of the Third Quartetdeparts from the traditional form. It consists of five relatively short movements which form a kind of symmetrical arch. B. Britten originally used the term divertimento as a working description of the quartet. Each movement of the cycle has its own subtitle: Duets, Ostinato, Solo, Burlesque, Recitative and Passacalia (La Serenissima). All movements are written in three-part form (ABA). The slow lyrical movements of the quartet form a kind of arches inside the composition. The first movement, Duets, is in a sense the most abstract of all five parts. The beginning resembles a “double spiral” (two voices are closely intertwined and are an exact copy of each other). In the second movement, Ostinato, the idea of an ostinato, where a musical pattern is repeated over and over in the background, takes on a somewhat intrusive form. In the third movement, Solo, the lone violin line, moving through wide intervals, is accompanied mostly by only one other voice at a time. In the fourth movement, Burlesque, the world of parody entertainment, clowning, buffoonery is presented. The fifth movement is entitled La Serenissima, a reference to Venice. In this movement B. Britten quoted his own last opera, Death in Venice. The results of the research support the idea that B. Britten’s late style refers to consolidated type of late style. This conclusion is reached based ona specific analysis of the Third String Quartet by B. Britten. The Third Quartet accumulates as features of B. Britten’s late style as the asceticism of expressive means in writing, reliance on the frets of folk music and the rigor of writing. B. Britten’s enthusiasm for the traditions of folk music resulted in a desire for the texture of all the voices in his instrumental scores. The composer’s chamber music is characterized by detailed instrumentation. Despite all the possibilities of using modernist techniques in the creative process B. Britten can be traced to an academic style. It is worth noting the amazing unity of B. Britten’s style throughout his life. Individual composer style is constantly being refined, remaining homogeneous at the same time (there are not style shifts and differences). In addition, B. Britten had always been aimed at performers and often wrote instrumental works on order. Although B. Britten’s heritage is widely represented in Ukrainian and foreign musical science, the specifics of the composer’s late style is still a field for study and comprehension. The paper opens up prospects for the study of the last opus in the late period of the work of composers.

The purpose of this study is to explore the literature for textless voice and woodwind instruments. The primary focus concerns the timbral and ensemble possibilities exploited in three twentieth-century works in which the voice is treated as an instrument i.e., without the usual preoccupation with textual meaning. An historical overview of vocal works with obbligato woodwinds and concerted works for textless voice serves as an introductory chapter. The variables of voice and instrument acoustical makeup, vocal vowel formation and instrumental voicings, volume, vibrato, resultant tones, range, and extended techniques (fluttertongue, special vibrato demands, non-vibrato, etc.) are the focus of the performance considerations for this study. Over thirty twentieth-century textless works for voice and at least one woodwind instrument were located. The three, chosen for this study represent different periods in the century, and present contrasting styles and musical merit: Aria (1931) by Jacques Ibert, Three Vocalises (1958) by Ralph Vaughan Williams, and Duos I (1976) by Nancy Chance. A style and performance analysis of these works with pertinent research on the composers is presented. Appendices include an annotated bibliography of selected works for the medium, a written interview with Nancy Chance, and performance notes provided by the composer, concerning Duos I.
