# Drum Trainer

Twenty-one participants learned to play two drumming patterns (pattern 1: AABA, pattern 2: AAABAA) at three different tempos (fast: 150 bpm, medium: 100 bpm, slow: 60 bpm). Responses were recorded using the f and j keys on a standard keyboard. Visual feedback in the form of a coloured circle coincided with each button press and indicated whether the response was early, on time, or late. Feedback was determined by comparing the response time, relative to the previous response, to a window around the target duration. The window was adapted trial-by-trial to ensure that roughly half the outcomes were "on time".

Participant 12 should be excluded from event-locked analyses due to bad triggers (trigger cable was partially disconnected).   

Timing  
Repeat for 72 trials: fixation dot (until response) -> feedback circle (50 ms)
