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.
