That also works well for me when I have a large amount of material to work on. I have a tendency to dwell too long on one particular section or weakness and end up not ever getting to other parts. I used 15 minute blocks per page of audition material with the goal of hitting every page at least once per day.Besson983 wrote:Have him set SPECIFIC goals for specific times dureing his practice. IE: First 10 min, work on first phrase in solo. Next 10, get Prokofiev clean, etc... The more specific the goal, the better.
That way, he is maximizing his time instead of saying, "Well, I'm going to work on sounding good today, so I'm going to play a lot of Kopprasch."
Do the same thing for solo material. Maybe 20 minutes per page. If you are working on very technical material which can't be sight read at a performance level then do the same timed intervals but also incoorporate SLOW steady metronome work on each page for a few weeks before clicking the tempo up SLOWLY. By the time you get up to full tempo in practice, perhaps 3-5 weeks/months or more, then the tune will be flawless and you will also have discovered phrasing and other musical ideas along the way that you would not have found if you were wasting all your mental resources just trying to survive the fast notes while hacking away at full speed for weeks. You will experience real growth instead of ending up right where you started and frustrated.
