LSJ’s music performance on practiced and unpracticed pieces before and after practice on the same day and after a 14-day delay (Test Trials 1, 4, and 5, respectively) as evaluated by experienced string players. Performance was evaluated on a 1–5 scale separately for intonation (A), rhythm (B), tone (C), and overall (D). Results were collapsed across the two practiced pieces, Piece A and Piece B. Error bars represent standard errors of the mean.
