Peer-reviewed Writings
This page hosts the list of all the peer-reviewed publications curated by an editorial team at the Analysis, Creation, and Teaching of Orchestration Project. This diverse range of writings — articles, essays, interactive projects, and reprints — focuses on timbre and orchestration research and scholarship. As an open-access online resource, it aims to provide a platform for academics, researchers, musicians, and educators to share their knowledge and insights on the study, understanding, and application of timbre and orchestration in various musical contexts. Submission Guidelines can be found here.
These publications cover a wide array of topics, such as the analysis of historical and contemporary compositions, the exploration of innovative orchestration techniques, pedagogical approaches to teaching timbre and orchestration, and the examination of cross-cultural influences on the development of these musical elements. By presenting a diverse selection of high-quality, peer-reviewed content, we promote collaboration, discourse, and the advancement of knowledge in this specialized field, ultimately fostering a deeper appreciation and understanding of the complex art of orchestration and the nuances of timbre in music.
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.

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.
A compositional technique where a musical line or melody is split between several instruments, rather than being played by a single instrument. Each instrument plays a note or a short succession of notes, creating a continuous melody with a constantly changing timbre or "tone colour.”
Suppose you enter a restaurant with a friend, mid-conversation. As you enter, you are greeted by the background noise of other patrons’ conversations. You and your friend begin to speak louder so you can hear one another. You’ve just experienced masking, a very familiar yet fascinating phenomenon that many of us encounter every day without even noticing.
In the process of analyzing the spectrum of a sound, it is sometimes useful to describe its spectral properties in terms of energy distribution rather than individually mapping all its components. In so doing, we invoke the concept of spectral envelope, a curve that can be obtained by successively connecting the peaks of the partials shown in the frequency representation of the sound (i.e., with frequency on the x-axis and energy or amplitude on the y-axis). Spectral envelopes are important factors in timbre perception. They reflect the acoustic properties of an object that produces sound in terms of the energy distribution across the frequency spectrum.
Just as a frequency spectrum makes it possible to analyze the partials and noise components that make up a sound, a spectrogram can be used to visualize the evolution of these components of a sound over time. The first modern device able to produce such a representation of sound was the “sound spectrograph,” developed at Bell Telephone Laboratories in the 1940s [1]. A spectrogram has a very intuitive way of displaying its parameters. Just as in a musical score, time is represented on the x-axis, frequency on the y-axis, and energy/amplitude is determined by the intensity/hue of the colors.
A sound’s timbre can be represented by a point inside a conceptual timbre space, a space where the axes are usually defined by the principal attributes (e.g., spectral centroid, attack time) that one would implicitly use to perceive or conceive any timbre in a given context. Timbre spaces are obtained using a statistical method called multidimensional scaling analysis (MDS), which generates a simplified multidimensional map from a series of perceptual distances between pairs of timbres (as measured in perceptual experiments). The experimenter then deduces the attributes (acoustic descriptors) that best describe the axes obtained. Timbre spaces provide us with complementary information to the neuro-cognitive mechanisms of timbre perception, and can also be a very useful compositional tool.
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.
This doctoral thesis presents how the orchestration of timbre is in- vestigated from a performer’s perspective as means to “unfold” im- provisational processes. It is grounded in my practice as a pianist in the realm of improvised music, in which I often use preparations and objects as extensions of the instrument.
In this edition of Amazing Moments in Timbre, I will explore the timbral representation of sex (and maybe death) in “Pur ti miro, pur ti godo,” the final love duet between Poppea and Nerone in Monteverdi’s opera (on a libretto by Busenello), L’incoronazzione di Poppea. Martha C. Nussbaum, in Upheavals in Thought (2012), describes the duet as “an extraordinary depiction of lovemaking,” presumably in part because of the tension and release created by the numerous harmonic clashes and resolutions in the piece. Meanwhile, music librarian and blogger Pessimisissimo interprets the dissonance as follows:
Passaggio, an Italian word translating to passage or transition, is the bane of many a classical singer and the secret weapon of folk-inspired vocalists like Dolores O’Riordan, Jewel, and Sarah McLachlan. In English we often refer to this as “the break.” One of the main goals of classical vocal technique is smoothing out register breaks. This requires finesse, patience, and perseverance. It is a process that cannot be rushed because singing in the passaggio for extended periods of time can mentally and physically tax even experienced singers, causing serious vocal fatigue.
An analysis of orchestration treatises and musical scores reveals an implicit understanding of auditory grouping principles by which many orchestration techniques give rise to predictable perceptual effects. We present a novel theory formalized in a taxonomy of devices related to auditory grouping principles that appear frequently in Western orchestration practices from a range of historical epochs.
In The Alchemical Wedding (1996), for large ensemble, Australian composer Liza Lim seeks contact points between “seemingly disparate musical entities” (1996)—a pursuit reflected in the work’s title. This virtual contact is evidenced by the work’s peculiar instrumentation, where the Chinese Er-hu and Indonesian Angklung are pitted against a large Western ensemble. Reflecting the cultural fusion of composer’s upbringing between Australia and various Asian countries, The Alchemical Wedding represents a marriage of musical possibilities through the collision of Asian and Western instruments and aesthetics.
Abstract: This short essay will investigate how Rebecca Saunders uses several orchestration techniques to create a timbral progression in her work dichroic seventeen in order to emulate the visual phenomenon of dichroism.
The opening section of the ensemble piece Pour l’image by Philippe Hurel is underpinned by a series of orchestration approaches that work in concert to generate large-scale musical transition. The first prominent transition happens in the first 15 measures, traversing from a complex timbral agglomerate to a transparent polyphonic texture. The second transition happens in mm. 22-45 where a harmonically and timbrally dissonant texture gradually condenses into a passage of consonant chordal echoes.
The purpose of the Musician’s Auditory Perception (MAP) project is to collect qualitative data via sonic ethnography in order to promote and analyze, both literally and metaphorically, (a) sonic collaboration between auditory learners, (b) modes of sound information gathering, and (c) the creative expression of musicians, while disrupting common pedagogic methods that reinforce hierarchical education practices.
"Masque de fer" (Iron Mask) is a module for exploring extended techniques on the drum kit, created by Gabriel Couturier and Martin Daigle who were awarded the ACTOR Project’s Collaborative Student Project Grant. The recording session generated an open-access extended technique resource that includes a stereo mix, the entire recording session, and the stems in 96 kHz or in 48 kHz. This session was filmed from the first-person point of view to allow researchers and composers to step into the world of the drum kit performer. This tool will allow composers to familiarize themselves with the sound possibilities which are presented in the research.
Composers make use of their knowledge of different orchestration techniques in creating certain effects and sonic outcomes. These effects may be comprehended by listeners to a greater or lesser extent depending on the amount of shared understanding with the musical tradition, style of music, and other factors. In this project, we look at how the success of these effects depends on both prior knowledge and experience, and how they are perceivable by listeners. Successful orchestration is built upon the fact that regardless of the instruments used or the musical or cultural connotations of the music, they adhere to universal mechanisms of auditory perception and cognition.
Sound is vibration! Repeated, continuous vibration of the air creates sustained sounds. Within sustained sounds, vibration modulations are a natural component of both vocal and instrumental music. Patterns of vibration modulations are perceived by the human ear, and we call them vibrato. Vibrato is commonly accepted to be a distinctive feature of musical sound, inextricably tied to artistic expression and timbre.
Blend is achieved when two or more timbres appear to “fuse” together. A particular blend of multiple timbres occupies a continuum between total fusion (completely blended) and total heterogeneity (not blended at all).
