A, Autocorrelograms of the response of musicians (left) and nonmusicians (right) for the consonant interval. The time indicated on the x-axis refers to the midpoint of each 150 ms time bin analyzed. Color indicates the degree of periodicity. The band of color ∼30.2 ms (indicated by arrows) is narrower (i.e., sharper phase locking) for the musicians than nonmusicians. This pattern is repeated at 60.4 ms, i.e., 30.2 ms ×2. B, Sharpness of envelope phase locking for the consonant interval as a function of years of musical training for all subjects (n = 26) including the amateur group. The longer an individual has been practicing music, the sharper the phase locking (i.e., narrower autocorrelation peak at 30.2 ms).
