An early, short report on the Piano Tutor.

You probably won't find this in your library. I tried to cover some of the "multimedia" aspects of the Piano Tutor in this paper written for a symposium. The chapter in Multimedia Interface Design covers roughly the same ideas:

A fairly early but detailed report on the Piano Tutor. Most of the stuff in this article was implemented as described, so it is a pretty good architectural description.[Acrobat Version]

This is the only paper written after the project was completed. It is a short paper about what we learned and includes the results from our pilot study.[Acrobat Version]
