"Czerny believed that finger development must be built solely on mechanical gymnastics. His method was one of endless repetition, of constant pecking at one spot…Czerny believed in first developing technique independently from music, then making this technique eventually serve the realisation of artistic aims. For the first time the full separation of mechanics and music was pronounced clearly and frankly."
