Schubert's Symphony No. 10 in D major, D 936A, is an unfinished work that survives in a piano sketch. Written during the last weeks of the composer's short life, it was only properly identified in the 1970s. It has been orchestrated by Brian Newbould in a completion that has subsequently been performed, published and recorded.

Franz Peter Schubert was an Austrian composer of the late Classical and early Romantic eras. Despite his short life, Schubert left behind a vast oeuvre, including more than 600 secular vocal works, seven complete symphonies, sacred music, operas, incidental music, and a large body of piano and chamber music. His major works include the art songs "Erlkönig", "Gretchen am Spinnrade", "Ave Maria"; the Trout Quintet, the unfinished Symphony No. 8 in B minor, the "Great" Symphony No. 9 in C major, the String Quartet No. 14 Death and the Maiden, a String Quintet, the two sets of Impromptus for solo piano, the three last piano sonatas, the Fantasia in F minor for piano four hands, the opera Fierrabras, the incidental music to the play Rosamunde, and the song cycles Die schöne Müllerin, Winterreise and Schwanengesang.
