(Rakhmaninov/Russian or Rachmaninoff/English translation) In the fourth movement, you can hear a xylophone performing some decoration during the brass motif, at least I think it's a xylophone. Question #1 - is it a xylophone, and if so... Question #2 - the xylophone isn't part of the romantic period orchestra (at least, as far as I'm aware). Is it a member of the modern era, and that was Rakhmaninov's influence to use it in his Symphony? Thanks for any insights!
