I love Tchaikovsky too , the Nutcracker suite and the piano concert 1b moll!
Toccata from Bach of course.
Peer Gynt from Edvard Grieg (Morning mood and Solveigs song are my favourites!)
Some compositions of Beethoven, Mozart, Brahms, Ravel and Chopin.
The opera Turandot. I love the song Nessun dorma!
And a lot of operettas from Strauss and Kalman. My favourite operetta is "Die Fledermaus"
All the walzes from Strauss
Uuuuu I can't stop!
