Anton Bruckner is best known for his symphonic works; there are 11 symphonies (the last with an unfinished finale), most of them in several versions. He also composed a few other smaller orchestral works (one overture, one march and three 'small orchestral pieces'), and sketched another symphony. Bruckner's chamber music includes one theme and variations and six scherzos for string quartet, one string quartet with alternative rondo, one string quintet with additional intermezzo, one duo for violin and piano, and about 50 small piano works.
