Melody Medley
Starting Hint
Apollo has taken a number of classical music (or rather Western art music) melodies and mixed them together into a larger work.
The piece is a set of five minipuzzles (and a separate minimeta). The puzzles are sections A-E; you can ignore the sections marked M# for now. The actual puzzle content are the parts marked in black and blue. Start with parts marked in blue; each is a hint for how the entire segment functions. You can safely ignore parts in gray; those are largely accompaniment to other pieces in the work, and are mostly to make everything sound nice.
If you get stuck, here's some further advice:
More on getting started
You will need to identify the actual pieces. The composers' initials are given as a hint. Musipedia is a great way to identify melodies of any kind, particularly classical. The medley may change a melody's key, rhythm, or tempo to fit its section; the contour, however, will always be the same.
Apollo, patron of the establishment where you now find yourself, has been hammering away at the piano. It's a grand composition, but he believes the qualities of the original works dominate in every case.
