Is the clarinet in this piece supposed to be Clarinet in Bb or Clarinet in A? Because I saw some notes that I don't think are possible on Bb Clarinet but might be on A.
@@gjdkdovm that's right, the alterations written here are the same as the other instruments, this means that if he would have been wrote already transposed we would see different (more or less) alterations for the clarinet part.
It is written in concert pitch in order to be possible to play on any clarinet in theory, but if you're true, this means Prokofiev didn't realize it's not possible on Bb
