Non-Standard Sound Synthesis with Dynamic Models
Full version unavailable due to 3rd party copyright restrictions.This Thesis proposes three main objectives: (i) to provide the concept of a new generalized non-standard synthesis model that would provide the framework for incorporating other non-standard synthesis approaches; (ii) to explore dynamic sound modeling through the application of new non-standard synthesis techniques and procedures; and (iii) to experiment with dynamic sound synthesis for the creation of novel sound objects.
In order to achieve these objectives, this Thesis introduces a new paradigm for non-standard synthesis that is based in the algorithmic assemblage of minute wave segments to form sound waveforms. This paradigm is called Extended Waveform Segment Synthesis (EWSS) and incorporates a hierarchy of algorithmic models for the generation of microsound structures.
The concepts of EWSS are illustrated with the development and presentation of a novel non-standard synthesis system, the Dynamic Waveform Segment Synthesis (DWSS). DWSS features and combines a variety of algorithmic models for direct synthesis generation: list generation and permutation, tendency masks, trigonometric functions, stochastic functions, chaotic functions and grammars. The core mechanism of DWSS is based in an extended application of Cellular Automata.
The potential of the synthetic capabilities of DWSS is explored in a series of Case Studies where a number of sound object were generated revealing (i) the capabilities of the system to generate sound morphologies belonging to other non-standard synthesis approaches and, (ii) the capabilities of the system of generating novel sound objects with dynamic morphologies.
The introduction of EWSS and DWSS is preceded by an extensive and critical overview on the concepts of microsound synthesis, algorithmic composition, the two cultures of computer music, the heretical approach in composition, non- standard synthesis and sonic emergence along with the thorough examination of algorithmic models and their application in sound synthesis and electroacoustic composition.
This Thesis also proposes (i) a new definition for “algorithmic composition”, (ii) the term “totalistic algorithmic composition”, and (iii) four discrete aspects of non-standard synthesis
Biomechanical Modelling of Musical Performance: A Case Study of the Guitar
Merged with duplicate record 10026.1/2517 on 07.20.2017 by CS (TIS)Computer-generated musical performances are often criticised for being unable
to match the expressivity found in performances by humans. Much research
has been conducted in the past two decades in order to create computer
technology able to perform a given piece music as expressively as humans,
largely without success. Two approaches have been often adopted to research
into modelling expressive music performance on computers. The first focuses
on sound; that is, on modelling patterns of deviations between a recorded
human performance and the music score. The second focuses on modelling the
cognitive processes involved in a musical performance. Both approaches are
valid and can complement each other. In this thesis we propose a third
complementary approach, focusing on the guitar, which concerns the physical
manipulation of the instrument by the performer: a biomechanical approach.
The essence of this thesis is a study on capturing, analyzing and modelling
information about motor and biomechanical processes of guitar performance.
The focus is on speed, precision, and force of a guitarist's left-hand. The
overarching questions behind our study are:
1) Do unintentional actions originating from motor and biomechanical
functions during musical performance contribute a material "human feel"
to the performance?
2) Would it be possible determine and quantify such unintentional actions? 3) Would it be possible to model and embed such information in a computer
system?
The contributionst o knowledgep ursued in this thesis include:
a) An unprecedented study of guitar mechanics, ergonomics, and
playability;
b) A detailed study of how the human body performs actions when playing
the guitar;
c) A methodologyt o formally record quantifiable data about such actionsin
performance;
d) An approach to model such information, and
e) A demonstration of how the above knowledge can be embeddedin a
system for music performance
Improvisatory music and painting interface
Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2004.Includes bibliographical references (p. 101-104).(cont.) theoretical section is accompanied by descriptions of historic and contemporary works that have influenced IMPI.Shaping collective free improvisations in order to obtain solid and succinct works with surprising and synchronized events is not an easy task. This thesis is a proposal towards that goal. It presents the theoretical, philosophical and technical framework of the Improvisatory Music and Painting Interface (IMPI) system: a new computer program for the creation of audiovisual improvisations performed in real time by ensembles of acoustic musicians. The coordination of these improvisations is obtained using a graphical language. This language is employed by one "conductor" in order to generate musical scores and abstract visual animations in real time. Doodling on a digital tablet following the syntax of the language allows both the creation of musical material with different levels of improvisatory participation from the ensemble and also the manipulation of the projected graphics in coordination with the music. The generated musical information is displayed in several formats on multiple computer screens that members of the ensemble play from. The digital graphics are also projected on a screen to be seen by an audience. This system is intended for a non-tonal, non-rhythmic, and texture-oriented musical style, which means that strong emphasis is put on the control of timbral qualities and continuum transitions. One of the main goals of the system is the translation of planned compositional elements (such as precise structure and synchronization between instruments) into the improvisatory domain. The graphics that IMPI generates are organic, fluid, vivid, dynamic, and unified with the music. The concept of controlled improvisation as well as the paradigm of the relationships between acoustic and visual material are both analyzed from an aesthetic point of view. TheHugo Solís García.S.M
Music as complex emergent behaviour : an approach to interactive music systems
Access to the full-text thesis is no longer available at the author's request, due to 3rd party copyright restrictions. Access removed on 28.11.2016 by CS (TIS).Metadata merged with duplicate record (http://hdl.handle.net/10026.1/770) on 20.12.2016 by CS (TIS).This is a digitised version of a thesis that was deposited in the University Library. If you are the author please contact PEARL Admin ([email protected]) to discuss options.This thesis suggests a new model of human-machine interaction in the domain of non-idiomatic
musical improvisation. Musical results are viewed as emergent phenomena
issuing from complex internal systems behaviour in relation to input from a single
human performer. We investigate the prospect of rewarding interaction whereby a
system modifies itself in coherent though non-trivial ways as a result of exposure to a
human interactor. In addition, we explore whether such interactions can be sustained
over extended time spans. These objectives translate into four criteria for evaluation;
maximisation of human influence, blending of human and machine influence in the
creation of machine responses, the maintenance of independent machine motivations
in order to support machine autonomy and finally, a combination of global emergent
behaviour and variable behaviour in the long run. Our implementation is heavily
inspired by ideas and engineering approaches from the discipline of Artificial Life.
However, we also address a collection of representative existing systems from the
field of interactive composing, some of which are implemented using techniques of
conventional Artificial Intelligence. All systems serve as a contextual background and
comparative framework helping the assessment of the work reported here.
This thesis advocates a networked model incorporating functionality for listening,
playing and the synthesis of machine motivations. The latter incorporate dynamic
relationships instructing the machine to either integrate with a musical context
suggested by the human performer or, in contrast, perform as an individual musical
character irrespective of context. Techniques of evolutionary computing are used to
optimise system components over time. Evolution proceeds based on an implicit
fitness measure; the melodic distance between consecutive musical statements made
by human and machine in relation to the currently prevailing machine motivation.
A substantial number of systematic experiments reveal complex emergent behaviour
inside and between the various systems modules. Music scores document how global
systems behaviour is rendered into actual musical output. The concluding chapter
offers evidence of how the research criteria were accomplished and proposes
recommendations for future research
Information technological aspects in the field of music. Overview
Uurimuse põhieesmärgiks on anda lugejale ülevaade nootide (noodilehtede) ettevalmistamist ja muusika esitamist toetavatest tarkvarapakettidest ning tutvustada olulisemaid aspekte, mis on seotud nende rakendamisega muusikavallas. Üksikasjaliku ülevaate esitab töö tulemusena valminud veebisõelmete andmebaas koos seda esitava veebirakendusega, mis sisaldab nimetatud tarkvarapakette iseloomustavaid kirjeid. Töö tekstiline osa, st dokument, kirjeldab kokkuvõtlikult olulisemaid aspekte koos mõningate tarkvaraliste näidetega.
Osutub, et kõige rohkem leidub internetis noodigraafika töötlemise ning diginoodiks teisendamise vahendeid – vastavalt 98 ja 13 rakendust. Nende valdkondadega seotud töö jaotistes sätestatakse erinevad kriteeriumid, mida nimetatud rakenduste andmebaasi kandmisel arvesse võeti, aga ka meetodeid ja probleeme, millega vastavate rakenduste kasutamisel arvestada tuleks.
Uurimust alustades oli üks esmaseid eesmärke koguda võimalikult palju informatsiooni intelligentsete muusikaseadmete, eelkõige elektroonilis-intelligentsete noodipultide kohta. Paraku leidub just nimelt selles valdkonnas kõige vähem vahendeid – kokku vaid 4 rakendust, millest reaalselt kasutatav on vaid üks.
Töös kirjeldatakse rakenduste võimalikke omavahelisi võrdlusmomente, analüüsitakse vaadeldava valdkonna nüansse ning tutvustatakse arenguperspektiive. Informatiivsuse huvides on esitletud aga ka tarkvarakomponente ja -pakette (sh raamistikke), mis kaudselt toetavad nootide (noodilehtede) ettevalmistamist ning muusika esitamist – kokku 55 kirjet.
Lisaks kirjeldatakse muusikaõpet toetavaid vahendeid. Nendest on andmebaasi kantud kokku 14 rakendust.
Antakse põgus ülevaade olemasolevatest huvitavamatest noodikogudest ning nende kasutamisvõimalustest; andmebaasi lisatud vastavalt 13 kirjet. Tutvustatakse aga ka uurimuse kontekstiga seotud bibliograafiat ning ühte tuntumat konverentsiseeriat (ISMIR), mille raames on paljud publikatsioonid valminud. Publikatsioonide loetelu on samuti lisatud töö käigus valminud andmebaasi – kokku 113 kirjet. Arvestades, et pakettide kasutajaliidesed on reeglina ingliskeelsed, on koostatud vastav inglise-eesti terminisõnastik.The main purpose of this thesis is to give an overview of the existing software packages and tools, oriented towards the simplification of musicians everyday work. Since the field is quite extensive, only a subset of the available software has been taken into account – mainly programs designed to support preparing and interpreting sheet music.
The thesis is divided into two major components – a database (appended on a CD), which contains all the information about the collected data (software, hardware, related bibliography, etc) and the document itself, where the criterions for comparing the software packages are listed and explained together with some illustrative examples.
The first two chapters of the document are dedicated to the ways of generating sheet music – describing and comparing the different software tools for displaying and editing sheet music using note graphics software. Also, an overview of intelligent music stands, which is still an underdeveloped branch in this field, is given. The third chapter of the document describes aspects of using music software as a learning intent complemented with some examples of a freeware program.
Additionally, a slight overview of digital (sheet)music archives together with some interesting examples is given in the fourth chapter. Also, the field-specific bibliography (comprising years 1989-2012) is presented in the fifth chapter. In consideration of the fact that almost all user interfaces of the software packages use English language, an illustrated English-Estonian dictionary of relevant terms is appended.
The database contains 184 entries of topic-related software packages – 4 intelligent music stand applications, 13 digital sheet music converter applications, 98 score editors, 14 study assistant applications and 55 miscellaneous applications; 13 digital note archives and 113 publications
