Beethovens first movement of his Moonlight Sonata or Mondschein Sonate. It gots his name by Ludwig Rellstab, who was a music critic from this time. Riding on a boat in the Vierwaldstädter See in Switzerland at night time he got reminded to this music like a little Serenade accompanied with guitar and so he named the piece Moonlight Sonata. I put it to a-minor, which makes it very guitaristic.
