Techniques for analyzing a musical performance of a sequence of events. The events have parameters, such as timing, pitch and dynamics. A processor inputs (1-2) the performance; accesses (1-4) a standard performance of the musical piece; identifies (1-6) and compares (1-8) mutually corresponding events and determines (1-10) one of a set of classes: correct”, “low” or “high”. A current marker is displayed on an area of a display. The marker's position depends on the classification and the position of the previous marker, whereby trends and changes in performance accuracy are easily detected during performance.
