How long should my daily practice should be?

   The hours of practice should depend on the age of the student. For students aged ten or below should not practice more than three hours. Students who are older should, health permitting, practice a little more than three hours if the student would like to aim to become a professional musician. (Of course, it is not the number of hours that matters but the quality of practice which should concern the students. As a student begins to become more familiar with instrument, the practice should become more efficient.) I remember over-practicing for 12 hours a day in my youth: 4 hours in the morning, 4 hours in the afternoon and 4 hours at night. (It is also very important to take regular breaks so that the muscles and tendons are not damaged in any way.)
