Abstract: A method and apparatus for studying music includes a music analysis system, which in conjunction with a proprietary storage medium, enables the user to comparatively analyze a recorded musical performance alone or in synchronization with a modifiable synthesized version of the same musical performance. The system further provides facilities for defining specific segments of the original and synthesized performances as well as means for re-orchestrating the synthesized performance, adding additional instrumental parts to the synthesized performance, changing the tempo of the synthesized performance on playback, and electronically displaying and/or printing the score of the synthesized performance. The invention further includes a proprietary storage medium containing data representative of the original musical performance, digital data representative of the synthesized performance and timing data. The invention further discloses a method for generating the data stored on the proprietary storage medium.
