Here is a link to the IMSLP page for D779: link.
Lerdahl and Jackendoff comment on the waltz's anomalous design, and Margaret Notley takes its oddities as proof that the A-major waltz is a true character piece, not just another waltz improvised for dancing. I discuss the formal design in detail in the review-article. In a subsequent blog entry, I will show how the striking 10+8+10+10 design can be easily understood as created through improvisation (following comments by Kofi Agawu on composition or recomposition as analysis).
