Piano Sonata No. 15 in D major, Op. 28, is a piano sonata by Ludwig van Beethoven. The name Pastoral or Pastorale became known through A. Cranz publishing of Beethoven's work, but was first coined by a London publisher, Broderip & Wilkinson. While not as famous as its immediate predecessor, Piano Sonata No. 14, it is generally admired for its intricate technicality as well as for its beauty. The sonata takes roughly twenty-five minutes to play with its intended repeats.
