Pace of notes per second is the total number of notes counted within a particular time interval. Sample sizes (n), mean ±SD, followed by minimum-maximum values are presented for each character. For each character, any means in bold followed by different letters in parenthesis depict significant differences at p <.05. a Measurement keys: DF1, delta frequency of sharp note section (HighF1− LowF1); DS1, duration of all sharp notes including interval notes; DS2, duration of all raspy notes including interval notes; DTS, duration of total song; HighF1, highest frequency of sharp note section; LowF1, lowest frequency of sharp note section; NN, number of notes along the entire song; NN1, number of sharp notes; NN2, number of raspy notes; Pace, pace of total song; Pace1, pace of sharp notes section; Pace2, pace of raspy notes section; PeakF, peak frequency along the whole song; PeakF1, peak frequency of sharp notes section; PeakF2, peak frequency of raspy notes section.
