Fig 3. Results of tonal discrimination task in random tone sequence condition.

(A, C) Performance of musicians (A) and non-musicians (C) as a function of the number of measures for quarter note (black curve) and eighth note (grey curve) conditions. The performance is plotted as the d-prime value. (B, D) Performance of musicians (B) and non-musicians (D) as a function of the number of notes for quarter note (black curve) and eighth note (grey curve) conditions. (E) Combined analyses of the quarter and eighth note conditions. Performance of musicians (solid curve) and non-musicians (dashed curve) as a function of the number of notes in a sequence. Horizontal dashed lines in all plots represent the chance level. Error bars are corrected S.E.M across participants. Stars mark the significant difference comparing to the chance level.
