Hey I`m 12, and I`ve been playing jazz piano for about a year and a quarter, and my teacher says I play at about a grade 4 level. But I don`t practice very much. So how long do you kids that are in grade 8 after a year or two practice each week?

Most instructors would prefer their students to practice at least thirty minutes to one hour a day. It would be great if you can practice more than that, because, of course, there are no time limits...
