Carl Czerny
Czerny left Vienna only to make trips to Italy, France (in 1837, when he was assisted by Liszt) and England. After 1840, Czerny devoted himself exclusively to composition. He wrote a large number of piano solo exercises for the development of the pianistic technique, designed to cover from the first lessons for children up to the needs of the most advanced virtuoso.
