This visual aid is a helpful tool in introducing the concept of Sonata Form. Users can see the progression of the form visually (via colorful bars that move with the music and a basic diagram at the bottom of the screen) even as they hear the piece unfold aurally. It is clear enough for students to access individually; however, I would suggest incorporating the page in a classroom situation to encourage more specific engagement with the form. Although there are some aspects of the presentation that may be lacking (no use of harmonic relationships via Roman numerals, for example), this provides the opportunity to encourage user participation. Students could be asked to supply cadential information or chord relationships based on what they hear and see already.
As was mentioned in the peer review, it is difficult to maneuver through the page at times as the mouse points are small and tricky to find. Also, the quality of the score is fuzzy when projected on a large screen.
