Do you know which grade it is?
BytomGirl: I wasn't familiar with this piece until last
Wednesday when I heard Variations on it by
Beethoven at the recital of Andres Schiff,
amazing that such short piece earned almost an
long variations.
Broblem12: Well done!
grThetrojan01gr: Good play but it's kind of much reverb :S
