In a first approximation, we defined the salience of a metrical accent as the number of different levels of pulsation to which it belongs. Metrical accents are based on a similar hierarchical cognitive structure-the hypermeter-which consists of a tactus (or main beat), slower pulses (perceived or implied pulse trains or metrical levels containing several tactus events), and faster pulses into which the tactus is subdivided (Cooper and Meyer, 1960 Lerdahl and Jackendoff, 1983 Palmer and Krumhansl, 1990 Handel, 1998). ![]() ![]() This suggests that raters might use strategies different from individual metrical, melodic or harmonic accent models to mark the musical events. When different accent categories of accents were combined together, correlations were higher than for separate categories ( r = 0.66). In both experiments, when combining all the raters into a single measure expressing their consensus, correlations between ratings and model predictions ranged from 0.43 to 0.62. Average pair-wise correlations between raters were lower for metrical (0.27) and melodic accents (0.37) than for harmonic accents (0.49). In an analysis-by-synthesis approach, model predictions were compared with data from two experiments, respectively involving 239 sonorities and 638 sonorities, and 16 musicians and 5 experts in music theory. The model extends previous research by improving on preliminary formulations of metrical and melodic accents and introducing a new model for harmonic accents that combines harmonic dissonance and harmonic surprise. ![]() We present a novel computational model of immanent accent salience in tonal music that automatically predicts the positions and saliences of metrical, melodic and harmonic accents. In the past, grouping, metrical and melodic accents were investigated in the context of expressive music performance. Immanent accents involve temporal grouping (phrasing), meter, melody, and harmony performed accents involve changes in timing, dynamics, articulation, and timbre. Accents are local musical events that attract the attention of the listener, and can be either immanent (evident from the score) or performed (added by the performer).
