Table 1 Descriptive data for seven drumming sequences with >25 beats.

Sequence number, mean and SD of the interbeat interval, and total number of beats in the sequence are shown. χ2 statistics and P values for a global test of autocorrelation in each sequence (testing for autocorrelation up to 10 lags) and a test of autocorrelation at the first lag, together with the number of beats over which significant autocorrelation was detected, are also given. Sequences were performed by male 17 (30, 49, 50), male 10 (112, 120), male 8 (6), and male 2 (88).
