Video Example 2. Moving graphic with audio representing pulsation positions and omissions during the maturation of Jondon through Mode 1. The timing profiles for the dundun soloist’s and accompaniment parts part are on the left and right, respectively. The ranges between minimum and maximum values of sounded notes are given in black, and the mean values are given in orange. In the solo part, β1 moves later from an initial mean of 53.9% to 59.0% and eventually 60.9% as δ1 is omitted, then moves earlier to 52.7% as γ1 is omitted. In the accompaniment, γ1 moves from a mean of 28.2% to 22.8% before being omitted. When γ1 is omitted, β1 moves earlier, from a mean of 58.2% to 55.7%
