Third movement of this great symphony which is, as usual in Beethoven's symphonies, a scherzo, here in F major and D major.
Joseph Haydn wrote minuets that are close to scherzi in tone β but it was Ludwig van Beethoven and Franz Schubert who first used scherzi widely, with Beethoven in particular turning the polite rhythm of the minuet into a much more intense β and sometimes even savage β dance.
Presto - Assai meno Presto means Fast - Much less fast.
Working my way backwards...
Amazing this! I'd love to be the proverbial fly on the wall watching you work. If I attempted something like this it would sound like the background music to a Hanna-Barberra cartoon...
IMHO it takes a potent mixture of courage and talent to successfully pull off a piece like this.
You do the Maestro proud friend!
