Hi Rojo!:wave:
The list is rather long. One of my childhood favorites is his Violin Concerto in D, Op. 61. Dramatic yet sublime, this piece is the perfect introduction to Beethoven. Then there are his great symphonies; I like all of them! If ask for specefic movements, the a list could be as follows-
3rd- the schzero
5th- 3rd & 4th
6th- 1st & 2nd
7th- 2nd
8th-1st
9th- 3rd & 4th
... and yes the first mvmt of "Moonlight" Sonata.
