"Schubert's most original contribution to the keyboard repertory is arguably his music for piano duet. Although familiar from the 18th century, keyboard music for four hands was largely restricted to ephemeral pieces or utilitarian arrangements of orchestral works. Mozart invested the genre with more ambition but, as with the lied, it was Schubert who took a marginal genre and made it central. His earliest works for piano duet were three fantasies (D1, 9, 48), while a modest rondo (D608) from January 1818 and four polonaises (D599) and a sonata (D617) of Mozartian proportions composed in Zseliz during the summer of that year mark the beginning of Schubert's sustained interest in the genre." Maurice J.E. Brown, Eric Sams and Robert Winter in Grove Music Online.
