Abstract: This paper proposes a definition of polyrhythm that affords classification of a wider variety of polyphonic textures along a set of characteristics derived from”composite rhythms,” i.e., the sequential presentation of event onsets reduced to a single strand. Examples of notated rhythmic polyphony from the Suter 1980 Corpus (https://polyrhythm.humdrum.org/) that have been encoded in kern for computational analysis using the composite tool (https://doc.verovio.humdrum.org/filter/composite/) are provided as case study. One of the advantages of this approach is that it allows for comparison across different types of ensembles, regardless of the number of instrumental parts. By dividing the polyphonic texture into contrasting rhythmic strands, aspects of metric orientation, rhythmic patterning, event density, coincidence, and salience can be assessed. It is argued that measures derived from composite rhythms not only afford more fine-grain characterization of rhythmic structures, but also provide an opportunity to address issues of perceived complexity using realistic musical stimuli.

Recording details:

Ispiciwin, meaning “Journey,” embarks on an unprecedented musical exploration, bridging cultures and perspectives. Winnipeg and Cree composer Andrew Balfour describes it as a dream collaboration, one that deepens the understanding of truth and storytelling from an Indigenous standpoint. With the powerful voices of Luminous Voices, alongside artists Jessica McMann and Walter MacDonald White Bear, Ispiciwin is an evocative testament to the transformative power of music and a small, but important step toward reconciliation.

Luminous Voices, Calgary’s professional chamber choir, was founded in 2012 by conductor and Artistic Director Timothy Shantz. Uniting local, national, and international artists and organizations to illuminate choral music of the past and present, spanning cultures and traditions, we engage audiences in Calgary and beyond through exceptional sonic experiences encompassing live and virtual performances, recordings, workshops, new commissions by contemporary composers, and community education and development. Luminous Voices comprises some of the best ensemble singers in the Calgary area, collaborating with singers and musicians from across North America.
