What is the most efficient way to practice? I think I'm really lost on this. Case in point: I practiced a set of pieces for almost a year for a evaluation/competition kind of thing, and I totally messed up and blacked out in several spots during my performance. What I did to practice most of the year is the typical H.S.--->H.T. routine, then after memorization I just played the pieces through once every few days.I know there must be a more effective way to practice than just playing the pieces through. I'm going to play in my first competition in about a month and will be playing the same pieces that I totally messed up on. I need to learn how to practice. Please help!
