Full textSome theories and technical approaches used to characterize the computer-assisted composition process are presented. Theories and techniques unusually used in the field of computer music are applied to the numerous problems raised by a musicology of electroacoustic music and its genetic ontology. A critical deconstruction of methods and tools used to characterize musical creation is developed and a novel conceptual tool is exposed, and formalized. The notion of object, which permits a multiscalar reading of the creative process, is described and an adaptation of the traditional electroacoustic toolkit is made neccesary by the object considered as a multiscalar seme. A prototype of a compositional system gives a first answer in order to present complexity

Full textThis thesis presents the design and implementation of a computerized workbench, for the composition, creation and programming of experimental music. This workbench offers editors of graphical representations of musical pieces, sounds and models of elastic couplings, close to the underlying physical models, which are used for the synthesis and analysis of sounds. Our workbench also includes application skeletons, reusable program modules and function libraries which give support during the programming of compositional algorithms and interactive musical applications. Finally, the thesis presents several generators of musical scores, in particular a generator of a piece for orchestra and piano concertant. Our workbench integrates these various representational systems of musical forms as well as tools to convert from one representation to another. Thus it offers the composers innovative means for the computer assisted composition of experimental music

Full textThis thesis studies three party interaction in the music improvisation context. We use this term to refer to the ensemble of interactions arising from the onstage coexistence of three constituents participants: the human instrument player, the computer and the computer operator/performer. The purpose of this study is to investigate the requirements arising out of such interaction as well as establish the framework that will allow the computer fulfil the double mission of operating both as player and an instrument. In this framework we first present Multi Factor Graph (MFG), a new memory model for musical sequences. MFG is a deterministic automaton that indexes played sequences, with the intention of dealing with pattern recognition and sequence generation. Inspired by the Factor Oracle (FO) automaton, MFG deals with two FO-related issues. First, it corrects FO’s false positives during string recognition. Second, as far as the computer improvisation domain is concerned, it corrects the errors in the estimation of continuation probabilities arising from the misinterpretation of the FO’s Suffix Link Tree (SLT) as an indicator for maximal suffix repeats. Secondly, we study with the help of graphs by examining the complexity of adding simple to more sophisticated and complex constraints to generation. We propose reduced, graph-based computational frameworks that are able to efficiently deal with each of the problems discussed earlier. Finally, by drawing together all elements developed throughout the first two parts, we employ MFG as a universal framework for managing problems of machine musicianship, namely music listening, constrained sequence generation and interaction

Full textThis thesis discusses the use of deep generative models for symbolic music generation. We will be focused on devising interactive generative models which are able to create new creative processes through a fruitful dialogue between a human composer and a computer. Recent advances in artificial intelligence led to the development of powerful generative models able to generate musical content without the need of human intervention. I believe that this practice cannot be thriving in the future since the human experience and human appreciation are at the crux of the artistic production. However, the need of both flexible and expressive tools which could enhance content creators' creativity is patent; the development and the potential of such novel A.I.-augmented computer music tools are promising. In this manuscript, I propose novel architectures that are able to put artists back in the loop. The proposed models share the common characteristic that they are devised so that a user can control the generated musical contents in a creative way. In order to create a user-friendly interaction with these interactive deep generative models, user interfaces were developed. I believe that new compositional paradigms will emerge from the possibilities offered by these enhanced controls. This thesis ends on the presentation of genuine musical projects like concerts featuring these new creative tools

Full textHow can the musical convergence between sound and image, between audio en video, be achieved when working with digital technology? What is "musicable" in the visual domain? I suggest that the musical convergence is achieved through the use of technological devices that allow to 1) establish a certain degree of interaction between the musical and visual media, and 2) manipulate visual materials through an ensemble of compositional operations that are coherent with a given musical paradigm. On this basis, we suggest that what is "musicable" in the visual domain is the ensemble of visual variables that can be manipulated during the compositional process, to the extent in which they make musical sense. The research begins by identifying the historical context that set the conditions for the musical convergence between visual and musical media. We then present a multiple case study that is integrated by 12 works which belong different stages of the history of visual music. The study reveals the use of 41 methods to craft the musical convergence between visual and musical media. The final chapter presents an artistic demonstration of the use of the methods and concepts that emerged from our multiple case study. The conclusions present a synthesis of the results, a discussion of the interaction between theoretical and practical approaches, and my personal reflections on the pathways for future research in the field

Full textThe development of computer assisted composition environments, intended for data-processing and formalization of musical structures, as been an important contribution for the contemporary musical writing, during second half of the 20th Century. Starting from a reflection on the influence that such environments brought to the musical composition, this study will propose a set of tools CAC which will try to give a new approach concerning these issues. This research will be based mainly on my personal experience as a composer, and will be based upon three fundamental aspects: 1 - Processes of composition - Creation of a corpus of processes of composition aiming its algorithmic formalization. 2 - Representation of the musical data - creation of a unit of visualization and listening tools for sound data and musical structures. 3 - Interaction Composer-Computer. Creation, experimentation and development of graphic user interfaces (ergonomic research) for each type of function or tool

Full textSOUND IS DEFINED AS THE JUNCTION BETWEEN A PHYSICAL PHENOMENON AND PHYSIOLOGICAL A PSYCHOLOGICAL REALITY. MEANWHILE, ONLY THE AUDITIVE PERCEPTION - ESTABLISHES ACOUSTIC PHENOMENON ITS SOUNDING SPECIFICITY. LINKING PHYSICAL DIMENSIONS WITH ELEMENTS OF HEARING IS A RESTRICTED IDEA. LEADING WORKS IN PSYCHOACOUSTIC SHOW THAT AUDITION CANNOT BE REDUCED TO THIS CONCEPT. SOUNDS HAVE TO BE CONSIDERED AS THE ELEMENTS OF AN AUDITION SCENE OF WHICH MUSIC IS A SPECIFIC CASE. THUS, IT IS NECESSARY TO ANALYSE SPECIFICITIES OF MUSICAL SOUND, FOLLOWING THE HISTORICAL WAY THAT LEAD TO A DEFINITION ARTICULATED AROUND PARAMETERS OF PITCH, DURATION, INTENSITY AND TIMBRE. THIS LAST DIMENSION APPEARS AS A CENTRAL VALUE IN CONTEMPORARY MUSIC. THIS TRANSITION FROM A MUSIC OF PITCH TO A MUSIC OF TIMBRE, TAKES A DECISIVE DIMENSION with THE BIRTH OF ELECTRICAL SOUND TECHNICS. IN THE TIME OF ONE CENTURY THOSE TECHNICS BROUGHT MUSICIANS A COLLECTION OF TOOLS THAT USES THE CAPACITIES OF SOUND TRANSFORMED IN ELECTRICITY THEN IN DIGITAL INFORMATION. AMONG THOSE RESSOURCES, THE SECOND PART OF THIS WORK TAKES SOUND SYNTHESIS AS SUBJECT. WE DISCUSS IN THIS PART OF DIFFERENT SYNTHESIS METHODS AND WE SHOW DIFFERENT PROGRAMMING EXAMPLES, SEPARATED IN TWO CATEGORIES. METHODS OF SIGNAL SYNTHESIS IN WHICH ALL THE PARAMETERS OF ACOUSTIC WAVES MUST BE SPECIFIED. PHYSICAL MODELING WHERE THE INTERACTION BETWEEN OBJECTS LIKE STRING, PLATE, TUBE, MASS, IS DESCRIBED BEYOND A TECHNICAL PROCESS, THE GOAL OF THIS WORK IS TO DEMONSTRATE THAT SOUND SYNTHESIS IS A GENUINE PART OF MUSICAL COMPOSITION TERRITORY. IT WOULD BE A MISTAKE TO REGARD ONLY AS A TECHNOLOGICAL PRODUCT

Full textA note in a score, as other musical objects, can be considered as an entity having some properties. These last are represented by atomic values in columns on a line of relational data base table. The representation of all notes in the score in relational form of tables as a totality of columns and lines facilitates the access to the music analysis of open character: each can interrogate following each problematic the database that represents and stocks the score. The score of Variations for orchestra op. 30 of Anton Webern, as an example of application of the concept of “Relational Database-aided Music Analysis”, is represented, stored, and analyzed in a classificatory and a paradigmatic way: All sets, all intervals, and all chords existing in the score are retrieved, as a result on can verify the dominant intervals and chords; the particularities concerned distribution of notes in the register, duration, intensity and orchestration are also recognized

Full textBeneath the level of the note lies the realm of microsound, of sound particles. The microsonic particles remained invisible for centuries. Recent technological advances let us probe and explore the beauties of this formerly unseen world. Microsonic techniques dissolve the rigid bricks of music architecture–the notes–into a more fluid and supple medium. This book is the fruit of a lengthy period of activity involving synthesis experiments, programming, and composition. Beginning with a few strands, it eventually grew into a lattice of composition theory, historical accounts, technical overviews, acoustical experiments, descriptions of musical works, and aesthetic reflections. A diverse body of information is presented in seven chapters. At this stage of development, the musical, technical, and aesthetic problems interweave

Full textWe propose a study on the composition potentialities resulting from the conjunction of the object sound concept and the progressive transfer of musical technologies to the digital media. Beginning with the sound object of Schaeffer, through the writings of other authors (Bayle, Smalley, Wishart), we arrive at the concept of digital sound object of Vaggione, which articulates this conjunction. Two consequences result: the statement of the enlargement of musical writing and a compositional attitude based upon the idea of a work as the result of an interface to a musical database (adapted from Manovich). Finally we describe the software and the works which guided us to two concrete results: a software for external patches management (KITTy) and the music for the “found footage” documentary Nature Morte which would not have been possible without the reflection and consequences presented here

Full textThis thesis aims at designing a computer system enabling the computation of musical structures, their presentation/handling on a compositional side, and their interactive rendering. It is a study at the crossroads between several computer science research fields : discrete systems modeling, scheduling, software design and human-computer interfaces. We propose an architecture where program editing can affect their outputs, including during the rendering phase, while preserving the compositional benefits of a deferred-time approach. Compositions are therefore considered as continually running programs, where computation and rendering mechanisms are interleaved. We introduce new tools and interfaces to arrange their execution through time thanks to dynamic temporal scenario scripting, which we call meta-composing.

Full textThis thesis on musical composition begins with a central inquiry: what are the underlying models of contemporary compositional practices? Stemming from this fundamental question, this study investigates the aesthetic and artistic currents that pervade today's creative landscape in the era of a post-digital society. It seeks to provide both a critical and theoretical framework for a series of works completed during this doctoral stage, founded on the utilization of metadata derived from natural models to generate various musical compositions, including interactive sound installations, participatory multimedia installations, sound gardens, pieces for orchestra and ensemble, online devices, and transdisciplinary collaborative creations. The objective is to propose different transcoding methods using this metadata, whether sourced from data streams on the web or from various electronic sensing systems. As part of the thesis, primarily tangible phenomena measurements (meteorological data, plant data, and brain electrical activity data) and environmental and physiological variables have been employed. These data have been structured and reinterpreted in order to convert them into not only qualitative musical parameters but also quantitative structures that allow variations of these parameters, ultimately constructing an articulated musical discourse or even musical categories. The study also reflects on the use of microtonality as a mean to generate a coherent harmonic and melodic universe from original models for each data stream transcoded into music. From this stage, it is proposed to reintegrate this material—with the diversity of its forms derived from nature and reinterpreted—by aiming to identify common or primary characteristics of each of these models as a reduced structural organization of a system, resulting in transient forms and articulation processes transitioning from one model to another through the development of artificial intelligence tools. Thus, this work anticipates the possibility of integrating various listening and concert experiences, discussing both participatory performance experiments involving the audience and compositions performed by ensembles of musicians, sometimes combining them into a single piece, paving the way for new forms of composition and musical practice. The audience thus becomes part of a genuine concert process, participating in the experience as music producers, with a multisensory immersive dimension made possible through the incorporation of extended reality technologies

Full textThis dissertation is the study of an experiment in a situation of collective electroacoustic composition from the point of view of the development of a community of practice. It was carried out in France, during the school year 2013/2014, in two classes of public elementary school Pasquier of the city of Antony located in Paris suburbs. We are therefore talking about a collective teaching of music to young children on school time realized in a co-teaching school between a teacher and a music teacher.Étienne Wenger's "theory of community of practice" will be used as a grid of reading and a prism through which we analyze the interactions of participants in an experiment of group music pedagogy conducted in school. We will study learning situations in this situation via inter-community and intra-community interactions, which are partly mediated by computer artifacts (audio files of musical selections, digital photos, publications and Internet availability, e-mail communication, etc.). As such, we have been interested in the use and the role played by information and communication technologies (ICT) in the exchanges of the community and in the theories of documentary sciences.Finally, we propose the construction of a pedagogical action model focusing on the interactions that we consider to be transposable to the university teaching of music composition in the Max and Pure Data environment in the Music Department of Paris 8 University
Petit, Bertrand. "Temps et durée : de la programmation réactive synchrone à la composition musicale." Thesis, Université Côte d'Azur, 2020. http://www.theses.fr/2020COAZ4024.
Full textThis thesis raises the question of the relationship between the expressiveness of computer programming tools and musical creation from the perspective of the expression of "time". We have based our reflection on time using the Bergsonian concept of "duration" which exists only in the consciousness of the perceiver as opposed to the objective time, which is that of clocks, independent of consciousness. We have chosen to follow the tradition of written music, i.e. preconceived in a fixed form that allows the composer to evaluate the aesthetic content of his work. Among the various possibilities of implementing duration, we have oriented ourselves towards interactive music, i.e. music that is controlled on stage, in part by the audience. We developed a method of composition based on three concepts: “basic musical elements” which are short musical phrases, “groups” of these basic elements, and “orchestrations”. The groups are made available to the audience who participates in the realization of the music by selecting one or another basic element or by responding to choices that will be proposed to them. The way in which the groups are made available to the audience constitutes the “orchestration” which is implemented by means of the synchronous reactive language HipHop.js. This language combines the programming of complex automata adapted to our orchestration concept, with web programming particularly adapted to the implementation of large-scale interactions. We fed this research with different experiments and musical productions using a software platform called Skini

Full textThis research/creation thesis is centred on the exploration of musicians’ needs for the practice of electroacoustic music improvisation. This investigation was conducted through participant observation with different musical ensembles. It also presents the strategies adopted for the development of digital tools in the case of a created musical instrument. How does the practice of free improvisation in electroacoustic music work and what knowledge is needed to achieve free improvisation? To answer these questions, several paths were taken: for example considering the context of the performance and by challenging the musical and extramusical aspects surrounding the improvised action. Furthermore, this research deployed a study of the characteristics of a digital instrument that endeavours to possess the same flexibility as acoustic instruments. The “creation” component of this thesis is through the development of a digital instrument (RJ). This instrument is implemented with a sound samples recommendation system. It was used in situation of improvisation with several ensembles, which form part of the corpus of data of this thesis. Lastly, this thesis seeks to characterize musical improvisation through the multiple interactions that occur during an improvised performance. The research therefore provides a practical and theoretical framework for the use and exploration of contemporary digital tools for musicians, which practice collective free improvisation
Carinola, Vincent-Raphaël. "Composition et nouvelles technologies : vers des nouveaux agencements des catégories musicales." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSES036.
Full textThe lexical evolution that tends to replace the terms "musical writing" or "composition" with that of “musical creation” or “sound art”, is an indication among others of the profound changes that the act of composition has faced, and of the difficulty of identifying many recent works as being created through a process of writing. These changes are obviously tied to evolutions in technology over the last century, especially pertaining to computing and digital tools – evolutions that have broken the link between musical work and traditional categories such as “score”, "instrument" or "performer", themselves sometimes seen to represent musical thought from a bygone era. Our thesis maintains however that the existence of these categories remains fundamental to understanding the concerns of composition, even in works where they seem to be absent. Indeed, one of the most important consequences of the transformations induced by new technologies is that traditional categories have been shattered into a multiplicity of technical objects whose interconnection can be considered as a form of writing. Discussed from the point of view of the evolution of musical technologies, each work appears as an “assemblage” (in the sense of “arrangement”), a new form of "concretization", to use Gilbert Simondon's term, of musical functions borne of technical means. Contemporary musical production bears witness to the immense variety of these assemblages

Full textThis thesis focuses on Arabic musical composition and new technologies, with the idiosyncratic characteristics inherent in the musical language as central element.The encounter with new technologies raises several underlying questions.The approach suggested consists of a formal frame with a set of idiomatic structures according to a pluridisciplinary angle musicological and ethnomusicological, but also historical-acoustical and theorico-empirical at the same time.The musicological model revealed underlines: the importance of primary melodic cells, acoustic quantification of interval systems, monody and heterophony aspects according to individual and collective level, instability of degrees, and aspects related to musical interpretation.Original approaches are envisaged concerning the study of the mechanisms of ornamentations and three categories are baptized.The confrontation of this musicological model with new technologies’ encounter is established and the consequences of this one are underlined.Simulation and emulation concepts highlight the centrality of timbre and the use of audio-visual samples allows the identification of the implicit domain of experimentation.A comparison with the experimental model of electronic music in general and computer music in particular is therefore made.Finally, a computational modelling test in the Csound environment is proposed and traces the idiosyncratic elements identified. Electroacoustic compositions are cited and a musical work is analysed

Full textWestern scholarly music has always benefited from the technological advancements available in each era. The influence such has proved to be, at the instrumental level, resulting initially in the broadening of the musical and compositional language and, subsequently, requiring the instrumentalist to adapt to new playing and interpretation techniques. The rapid technological development which marked the twentieth century pushed this situation to limits previously inconceivable. This is the origins of mixed music, which is a new kind of music that combining electro-acousitc music and acoustic instruments. Our thesis proposes a study on the trends of mixed music in France since 1981. First, we will analyze the main concepts inherent to the subject as well as their issues. Then, we will head towards the organization of the social, economic, political, cultural and musical environment existing in France which allowed the development of this musical genre. Lastly, we will focus on the idea of musical research to trace the main lines of mixed music trends in France since 1981. To do so, we will use musical works that are representative of this multidisciplinary work wich characterizing musical research

Full textIn this thesis, we will study a new approach in the practice of musical time composition starting from a notational concept dedicated to the writing of duration, rhythm and musical form. This new concept that we call Time Unit opens on several questions and issues structured around three key principles : the notation of Time Units, their operability (the potentiality to yield new musical form) and quantization. After examining these different approaches on time, form, duration and quantization, we shall try to create a new grammar of musical time directed on its syntax and its representation. We shall build tools for rhythmical transformation and production of Time Units. Once this is achieved, we will study the same Time Units under their real time aspect raising the issue of “compositional” and its implications on the scope of musical form. After a thorough study on symbolic rhythm quantization of Time Units structures we will explore the path starting from the conception of a composition, through its state of sketch, to its final state achieved by a “correct” quantization preserving the integrity of its discourse. This will be illustrated with case study examples, from our personal works

Full textThis thesis concerns the conception and development of a computer-assisted navigation sys- tem for endovascular surgery. The clinical application is the treatment of abdominal aortic aneu- rysm. The objective is real-time tracking, in pre-operative CT images, of the position of an aortic endoprosthesis inserted in the femoral artery. This research deals with the deưnition of relevant data from imaging and localization systems, as well as their processing and registra- tion for a minimally invasive navigation. The arterial tree is located in the Operating Room reference system through freehand ultrasound. An original 2D/3D registration method, based on prior knowledge, provides the transformation to register ultrasound images and pre-operative CT volume. The magnetic sensors' integration within the vascular guide allows a non invasive localization of the endoprosthesis inside the patient's aorta. Fusion of images and localization data permits real-time calculation of anatomical CT slices that correspond to the position of endovascular elements. The navigation system oers thus a non-radiative 3D visualization of the endoprosthesis. This thesis comprises several domains of computer assisted surgery : CT and ultrasound registration, calibration of magnetic and optical localization systems, calibration of a freehand ultrasound probe, and the conception of tools for a minimally invasive intervention.

Full textThis thesis discuss of the use of immersive environments of Virtual Reality (VR) for Computer Aided Design (CAD). We study how these new interfaces between man and information systems can improve the different tasks of geometric shape design that are actually done on workstation with screen. These workstations essentially use keyboard, mouse and graphical interface. However this kind of interaction does not take advantage of VR possibilities in term of direct 3d interaction. In addition, CAD objects does not allow ways to modify there shape with a direct and 3d interaction. We present an approach of reactive objects that allows changing the value of operations parameters in the construction history graph of the solid, from direct interaction of the user on the elements (vertex, edge, face) of the B-Rep of the solid. To this purpose, we use an inference system that decides what parameters to modify knowing the selected element, and how to map the manipulations of the user to numerical changes of the parameters. These inferences are based on sets of rules dealing with construction information attached to the elements of B-Rep. This model of reactive objects has been implemented in a software prototype allowing creation and modification of CAD objects in an intuitive way. The interface proposed is a multimodal and immersive environment. We also propose in this thesis a method for collision detection dedicated to immersive interaction and a graphic rendering system on PC cluster adapted to deformable objects

Full textFrom a musicological interpretation of the scientific notion of “modeling and simulation”, this thesis presents an approach for computer-aided analysis where musical scores are reconstructed from algorithmic processes and then simulated with different sets of parameters from which neighbouring variants, called instances, are generated. Studying a musical piece by modelling and simulation means to understand the work by (re)composing it again, blurring boundaries between analytical and creative work. This approach is applied to three case studies: an isolated technique, Pierre Boulez Chord Multiplication, which is explored through the prism formed by the theories of H. Hanson, S. Heinemann and L. Koblyakov; the piece Spectral Canon for Conlon Nancarrow (1974) by the american James Tenney (1934-2006) to which the computational simulation from different sets of parameters was taken to its ultimate consequences when a “space of instances” is created and strategies of visualisation and exploration are devised; and finally “Disorder”, the first piano study written by austro-hungarian György Ligeti in which the concepts of “combinatorial tonality” and “decomposition prime numbers”, applied to durations, are used to maximize the potential that a model has to produce different variations of the original piece

Full textThe Electron Beam Melting (EBM) process allows to build metallic parts from powder. Thanks to the geometric and mechanical quality of the parts produced, the EBM process can be used to manufacture functional parts and not only prototypes. This process, with other additive metallic processes, make it possible to consider a transition from 3D printing to metallic additive manufacturing.The use of additive manufacturing in an industrial environment requires compliance with quality, cost and time criteria for the parts produced. The production of manufactured parts involves a series of numerical stages which is called the numerical chain. The numerical chain has a significant impact on the three criteria mentioned above. Thus, this thesis provides an answer to the following question:How Computer Aided Manufacturing can improve the quality, cost and time of the EBM manufacturing process?This problem is addressed through the following underlying question:What are the required characteristics for a Computer Aided Manufacturing system adapted to the EBM process?In order to answer this question, the current numerical chain is analyzed. Three main limitations are found:- the use of STL files format- the process cannot be optimized at different scales- the process cannot be simulatedTo solve these issues, a CAM environment is proposed. It allows the centralization of all numerical operations in a single environment. All supported formats can be used within this environment, such as native CAD file formats or STEP format. Software developments are done to prove the feasibility of such an environment.The CAM environment implementation reveals the crucial role of simulation in this system. It is therefore necessary to answer this second question:How to obtain an EBM process simulation allowing the development of parameters, virtually?Although EBM simulation is a recurrent subject in scientific literature, existing studies are based on the finite elements method but the calculation time needed is too important to be used in an CAM environment. Thus, an alternative type of simulation is created in this thesis: a simulation based on abacus. It is composed of a finite elements model, that allows heat maps generation for standards cases of heating and cooling. These heat maps are then transformed in abacus. The simulation algorithm based on abacus search the nearest abacus from the simulated situation in order to estimate the temperatures at the next time step.This simulation method was used to reduce the calculation time while keeping a sufficient precision to optimize process parameters.With the simulation based on abacus, a tool for the optimization of melting strategies is developed. This tool allows quality improvement for the produced parts through the calculation of melting strategies according to thermic criteria.To summarize, the main contributions of this work are:- the definition of requirements specifications of a powerful numerical chain for the EBM process- the development of a CAM environment adapted to the EBM process- the proposal of a fast simulation for the EBM process, based on abacus- the development of a tool for the optimization of melting strategies

Full textPhysical model synthesis offers an approach to composition alternative to the more usual signal processing. Considering the musical phenomenon as a "unicum" emerging from the interaction between the musicians and their instruments the physical model synthesis realizes and gives phenomenological and sensitive corporeality to the creative actions. By conceiving not as separate entities sound material and musical structure directs the potentialities of the computer and creates an original and fruitful dialectic between the formal (structural) and perceptual (cognitive).The sphere of action for my PhD concerns the development, formalisation and categorisation of structural models – created by physical modelling – useful for musical composition in the perspective to highlight the musical formalisation function associated with the CORDIS-ANIMA physical model simulation paradigm.The starting point for this work is 20 years of personal use as a composer, of the GENESIS physical model musical creation software developed by the ACROE-ICA laboratory.This experience has led me, through works both scientific (modelling) and artistic (music composition), to consider this environment not as a synthesis tool, but as a complex instrument, which allows to create a complete musical composition covering all three usual categories of acoustics and music: micro-formal (the tone, harmony, orchestration), mezzo-formal (the rhythm, melody, and the basic sequences/harmonic structures) and macro-formal (the higher level harmonic structure, the formal outline of the entire composition).My goal is not to propose the framework of a new music or a new aesthetic, but develop "well-tempered" instruments for a new practice of music creativity that explores and accomplishes better the potentialities of computer and digital technology. This also leads in the direction of broadening the dialectic instrumentality - writing music to a "supra instrumentality" [Cadoz6] and to post-scriptic outlook on musical creation [Cadoz7]

Full textMedical imaging and its exploitation by computer methods provide new tools for surgeons in order to increase their precision during interventions. This thesis. St~d!es the preoperative planning step of tumor thermal ablation. The aim is to develop mtmtIve and automated tools to assist the selection of an optimal operative strategy, specifie to each intervention. We propose an original approach inspired by declarative modelling in CAD. This approach considers basic planning rules defined by experts as data, possibly modifiable and adaptative regarding their use. In this goal, we propose a constraints definition language in order to express them in a simple way. We also developped a generic solver that adapts itself to defined contraints. The sol ver detects the solutions set associated to each case and proposes optimal intervention strategies. We have also developped sorne interface tools in order to provide to the surgeon an intuitive planning software, displaying precious information for the choice of an operative strategy
