Category I (Numbers 1–9, tasks without usage of instruments) contains the training items for the first 2 weeks; Category II (Numbers 10–14, tasks with usage of instruments) contains the training items for the latter 2 weeks. *One action per beat, except for those indicated otherwise in the specification. ^#The average tempo obtained at the baseline; ^§ the average tempo achieved at the end of the study. bpm, beats per minute.
