Carl Czerny

Carl Czerny was an Austrian composer, teacher and pianist of Czech origin. His music spanned the late Classical and early Romantic eras. His vast musical production amounted to over a thousand works and his books of studies for the piano are still widely used in piano teaching. He was one of Ludwig van Beethoven’s best-known pupils and would later on be one of the main teachers of Franz Liszt.
