The Piano Sonata in E minor D 566 by Franz Schubert is a sonata for solo piano written in June 1817. The original manuscript appeared to lack a finale.[1] Ludwig Scheibler (1848-1921) was the first to suggest in 1905 that the Rondo in E, D.506 might be that movement.[2] The British composer and musicologist Kathleen Dale produced the first edition using this suggestion in 1948.[3] The 1976 Henle edition by Paul Badura-Skoda followed the same practice.[4]
