A Computational Model of Immanent Accent Salience in Tonal Music. Bisesi, E., Friberg, A., & Parncutt, R. Frontiers in Psychology, 10:1–19, Stockolm, Sweden, mar, 2019.
Paper doi abstract bibtex We describe the first stage of a two-stage semi- algorithmic approach to music performance rendering. In the first stage, we estimate the perceptual salience of immanent accents (phrasing, metrical, melodic, harmon- ic) in the musical score. In the second, we manipulate timing, dynamics and other performance parameters in the vicinity of immanent accents (e. g., getting slower and/or louder near an accent). Phrasing and metrical accents emerge from the hierarchical structure of phras- ing and meter; their salience depends on the hierarchical levels that they demarcate, and their salience. Melodic accents follow melodic leaps; they are strongest at con- tour peaks and (to a lesser extent) valleys; and their sali- ence depends on the leap interval and the distance of the target tone from the local mean pitch. Harmonic accents depend on local dissonance (roughness, non-harmonicity, non-diatonicity) and chord/key changes. The algorithm is under development and is being tested by comparing its predictions with music analyses, recorded performances and listener evaluations. 1.
