Abstract: The current study investigates the influence of pitch and register (ordered vs. randomized) on listeners’ ratings of five emotional dimensions (mood, energy, movement, dissonance, and tension) using excerpts from multi-part musical compositions that feature complex rhythmic and pitch structures. In addition to listeners’ ratings, computational measures derived from nine rhythm and pitch features were used to assess the influence of specific structural elements on listeners’ perceived emotions. The results show a large main effect of pitch presentation on all five emotional dimensions. Participants tended to rate ordered excerpts as more positive in mood, higher in energy, and with a greater impulse to move along the music, while randomized excerpts were perceived as more dissonant and more tense. Several rhythmic and pitch features were also reliable predictors of listener’s ratings, providing support for the use of naturalistic stimuli accompanied by more fine-grain measures of structural elements in experimental studies of listeners’ experience of music.

Abstract: Research on listeners’ perceived emotions in music draws on human and synthetic stimuli. Although research has shown that realistic synthetic audio can convey emotions, studies that compare listeners’ experience of synthetic audio and human performances are limited. Using short musical excerpts, we investigate the effect of performance (human vs. synthetic) and instrumentation (piano vs. string quartet) as well as the influence of twelve musical features on participants’ ratings of five emotional dimensions (mood, energy, movement, dissonance, and tension). Findings show a small main effect of performance and a large main effect of instrumentation. Synthetic audio was perceived as more positive in mood and less tense than human performances. Piano excerpts were also perceived as more positive and as conveying less tension and energy than synthetic excerpts. Several rhythmic and pitch measures were reliably predictive of participants’ perceived emotions, supporting the need for considering finer-grain structural features when using naturalistic stimuli.

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.
