The Real-time Timbral Analysis for Musical and Visual Augmentation project explores the potential of real-time machine learning (ML) techniques to create dynamic visuals in the context of musical improvisation and composition. This artistic research aims to enable musicians to interact with visuals that respond directly to their performance, thereby guiding listeners' perception through visual representations of changes in timbre and spectrum. The project incorporates software tools such as sp.tools, FluCoMa, Max MSP, and TouchDesigner to achieve real-time instrumental augmentation for musicians, offering a unique way to visualize musical parameters.

The repertoire of Chinese composer Wenchen Qin is often characterized by immediate connections to the topics of nature and religious spirituality. For Qin, the religious connotation in his music often serves specifically as the medium connecting humans and nature. One only needs to look at the titles of his works to see the prevalence of these two topics: Pilgerfahrt im Mai (Pilgrimage in May) (2004), The Nature’s Dialogue (2010), The Border of Mountains (2012), The Cloud River (2017), The Light of the Deities (2018), Poetry of the Land (2020), among others. Qin’s proclivity for these topics can be traced back to his childhood in Inner Mongolia where he was born. The vast landscape of Inner Mongolia, with its endless grassland interspersed with surging mountain ranges, bears a palpable trait of ruggedness and broadness of space, of which one can often identify musical counterparts in Qin’s music almost viscerally.

As an ensemble of four instruments from the same family, the quartet has an exceptional capacity for blending but can also sharply differentiate the timbres of its members when desired. Ans an uncoducted ensemble, the string quartet depends on close non-cerbal communication between its members, and quartet members are accustomed to making subtle variations in their playing to achieve timbral and orchestrational ends. The purpose of this project is to explore how composers can orchestrate for the string quartet, examining strategies for timbral blend, stratification, modulation, and contrast.

“Timbrenauts” is a cross-institutional collaborative student research-creation project. We employed experimental designs from timbre perception research to generate data models that will inform the creation of new musical compositions for an atypical instrumental duo of cello and trombone, while leveraging extended techniques rarely explored in traditional musical repertoire. In this TOR module, we discuss our motivations, data collection process, similarity judgment experiment, and the resulting data we want musicians to use as a basis for their creative output.

The primary objective of the Space As Timbre (SAT) project is to conduct meticulous experiments on orchestration solutions and playing techniques, to achieve timbral effects that closely approximate the perceptual characteristics of diverse acoustical spaces. To this end, SAT endeavors to illuminate the intricate interplay between the spectral content of a sound, its resynthesis through orchestration, and the resulting perception of the quality of the acoustical space where the sound seems to have been produced.

How do Luvale musicians tune their drums with heat and tuning paste? How does this tuning process change a drum’s timbre? How do practitioners describe these timbres? And what acoustic properties are encoded in these semantic, descriptive terms? In this collaborative and interdisciplinary module, we address these questions through the case study of a two-step tuning process among Luvale drummers in Zambia.

Professor Bad Trip: Lesson III (2000) is a piece for small ensemble composed by Fausto Romitelli, constituting the last part of his Professor Bad Trip triptych (1998–2000). As suggested by the title, Romitelli sought an aesthetic that evokes hallucination, plunging the listener into a state of illusion and bewilderment.

In raising the question of form-bearing dimensions in music, we are trying to understand the possibilities and limits of the apprehension of musical form in terms of the psychological mechanisms that operate on a received acoustic structure.

In the aftermath of World War Two, Luigi Dallapiccola (1904-1975) was famous for a few major works that conveyed a humanist message, particularly the Canti di Prigionia (1938-1941) and the opera Il Prigioniero (1944-1948), which rank among his better-known works to this day. The composer’s personality should, however, not be reduced to this one aspect of his output. Likewise, we should not merely see him as a practitioner of twelve-tone techniques inherited from Schoenberg and Webern, a facet that has been extensively explored by theoreticians and historians of music.

We might think about how a single voice part within a composition expresses a mode (one of the prevailing systems governing the organization of pitch in this period), or how multiple voice parts move against one another (counterpoint, from the Latin contrapunctus—literally means note-against-note), creating successions of intervals. This essay focuses on the amazing moments ensconced in those intervals: the way they are arranged, the spaces between them, and ultimately, the sonorities they create.

Roger Reynolds is Distinguished University Professor Emeritus of music composition at the University of California, San Diego. In 1989, he won the Pulitzer Prize for Music for the string orchestra composition, Whispers Out of Time. His more than 150 compositions have been exclusively published by Edition Peters New York for over five decades.

Nicolas Ellis is Music Director of the Orchestre National de Bretagne, Principal Guest Conductor of Les Violons du Roy, as well as Artistic Director and Conductor of the Orchestre de l’Agora, which he founded in Montreal in 2013. Known for his versatility in a vast repertoire, Nicolas has distinguished himself with the Orchestre de l’Agora by the conception of concerts with a dramaturgical approach.

This paper proposes an examination of the intersections of materiality, acoustics, and musical performance practice through the prism of instruments of the tuba family. Investigation into the symbiotic relationship between instrumental evolution and performance practice is a crucial facet of any study of timbre and orchestration.

This module offers a streamlined resource for emerging composers seeking to introduce live electronics into their instrumental orchestration practice. Accessible and user-friendly software and hardware platforms offer a pathway for emerging or (technologically curious expert) composers to experiment with electronics in a low risk, low-cost context.

This project spurred the development of an internet-based guide for musicians that describes, in layperson terms, the fundamentals of acoustic features of musical instruments, stages, and performance/rehearsal rooms using visual and auditory examples. The guide also aims to explain what and how parameters can be assessed along with the audio recordings to document a musical performance.

The DaTE project investigated the use of dance tracking to control electroacoustic processing of acoustic timbres. To this end, the project involved a composer/ programmer, a dancer, a flautist, and a cellist, and used the UBC-developed Kinect Controlled Artistic Sensing System (KiCASS) to track the dancer and generate movement/position data. T

This project analyzes the understudied parameters of timbre and texture and their interactions with musical form in a new popular-music corpus, Timbre in Popular Song (TiPS). This study addresses two problems in popular-music scholarship: lack of research on timbre and texture, and underrepresentation of non-male and non-white artists in both popular music and its scholarship.

In late August of 2022, the rich sonority of the historical Chapelle du Grand Séminaire de Montréal presented the acoustical canvas for a multifaceted choral recording and research project. Under the baton of Andrew Gray, Montreal choir Voces Boreales performed Joby Talbot’s Path of Miracles for mixed chorus (2005) and percussion, a musical pilgrimage for 17 voices, inspired by the millennial Camino de Santiago de Compostela.

Icicle (1977) for solo flute, by Canadian composer, conductor, and flautist Robert Aitken, captures a quintessentially winter soundscape with its highly variable timbral palette. Audible right from the beginning of Nina Assimakopoulos’s 2021 recording, Icicle is saturated with timbres that evoke such cold, wintry imagery as glistening icicles and blowing snow. The wintry timbres in Icicle are created by various extended playing techniques.

Kaija Saariaho’s Petals (1988) transforms the cello into a diverse musical instrument capable of creating countless varying sounds. Her organization of sounds produces two distinct timbral profiles that alter throughout the work, governing its two-part structure. Different music variables, including temporal perception, sound characteristics, spectral density, and attack, are employed by each profile to construct several binaries that either produce a state of tension or relaxation. The superimposition of profiles towards the end of Petals begets the work’s climax by maximizing tension. Saariaho therefore develops a narrative that explores opposing approaches to the creation and dissolution of tension through timbre.
