Phase alignment of phase angles in single trials related to behavioral asynchrony of play onsets between the two guitarists. (A) Asynchrony defined as the time difference (in ms) between play onsets of the two guitarists (guitarist B's play onset time minus guitarist A's play onset time) across 58 trials. (B) Time course of phase angles across trials (unsorted). (C) Phase alignment of phase angles at the two frequency bins (3.3 and 4.95 Hz, the second and the third harmonic of the metronome frequency) across trials in guitarist A. Trials were sorted by behavioral onset asynchrony between the players as shown in A. Behavioral asynchrony is depicted by the black curve. (D) Phase alignment of phase angles at the two frequency bins across trials in the guitarist B. Trials were again sorted by behavioral onset asynchrony between the players (guitarist A's play onset time minus guitarist B's play onset time), depicted by the black curve.
