Abstract: A device (1) for monitoring the use accuracy of percussion instruments (5) which includes a sensor (3) intended to detect musical data (T, I) from said instrument (5), an electronic device (9) adapted to sample at a sampling frequency Fc the musical data (T, I) detected by said sensor (3), which comprise the instant (T), detected with respect to an initial instant T0 taken as a reference, and the intensity (I) of each stroke that reaches the percussion instrument (5) during an execution of a musical score (PMS) played by a user (100), and adapted to store said musical data (T, I) in a memory device (11).
