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.
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 this Dialogue, New discusss the unique instrumental combinations and timbres that Holst employs to evoke the distinct characteristics of each movement. She delves into the challenges of balancing the various sections of the orchestra, crafting effective phrasing, and interpreting the composer's intentions to create a cohesive and compelling performance.
Tianyi Lu shares her approach to conducting and the role of timbre and orchestration in evoking emotions and immersing audiences in the musical experience, offering a unique perspective on the art of conducting.
In this interview, Kent Nagano, then Artistic Director of the Orchestre symphonique de Montréal (OSM), shared his thoughts on the essential role of timbre in music, the power of imagination in interpreting scores, and the art of communicating musical ideas to the orchestra.
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.
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:
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).
