Fig. 1: Average downbeat delays of soloists as a function of tempo.

Each point in the scatter plots corresponds to a piece of the Weimar Jazz Database29. In order to ease readibility, the corresponding standard deviations are shown in Supplementary Fig. 1. a Average downbeat delays in milliseconds as a function of tempo in beats per minute. The red line delimits the tempo range of pieces used in our experiment (see “Methods” section) and corresponds to the fit in (b). The scattered data exhibit mostly positive delays with generally a nonlinear trend, which is nearly linear in this restricted tempo range. b Average downbeat delays expressed in ticks as a function of tempo. The red line shows a linear fit to the data.
