Danish pianist Ludvig Schytte (1848-1909) was not prolific as a composer. His fame comes largely from his teaching and from the exercises he composed for such instruction. Niels Gade and Franz Liszt were two of his accomplished teachers. His music is still in use in modern piano studios in much the same way as Czerny's even if his output is nowhere near as large. He also composed two operas, a concerto, and a sonata to go with his etudes and exercises.
