Description: Czerny taught piano 10-12 hours a day; his genius for teaching was so cultivated that he could quickly devise the correct study for a student who exhibited a particular weakness. "Daily Excercises" is a collection of such studies. The compser recomends that about one hour be devoted to studying part of them every day, requiring about three or four days to get through all 40.
