This study centers upon a piano learning and teaching environment in which beginners and intermediate piano students (N = 48) learning to perform a specific type of staccato were submitted to three different (group-exclusive) teaching conditions: "audio-only" demonstration of the musical task; observation of the teacher's action demonstration followed by student imitation ("blocked observation"); and observation of the teacher's action demonstration while alternating imitation of the task with the teacher's performance ("interleaved observation"). Students submitted to "interleaved observation" were more proficient at the learned task with no significant differences for students of different proficiency levels.
