An electronic device and method for objective testing of proficiency in the performance of scales, arpeggios, and other standard musical exercises, and for evaluating the results according to recognized standards of perfect pitch and rhythm. A combination of microprocessor, digital signal processor, memory, and user interface (2, 5, 8, 3) creates and stores a test sequence as played by a musician, and also the same test sequence as produced by the testing device, the latter being made audible during the test (6). The microprocessor then analyses and compares the two versions of the test sequence, sending various kinds of reports to the output printer or video display (7).
