 7 is the name given to a four-movement symphony in E major (D 729) drafted by Franz Schubert in August 1821.Although the work (which comprises about 1350 bars) is structurally complete, Schubert only orchestrated the slow introduction and the first 110 bars of the first movement.The rest of the work is, however, continued on 14-stave score pages as a melodic line with occasional basses or counterpoints, giving clues as to changes in orchestral texture.
