Attack the Tough Spots
This is not just our opinion—it is how mastery is actually built.
- The research on expert performance calls it deliberate practice: you improve by working at the edge of what you cannot yet do, not by repeating what you already can.
- Studies of musicians in the practice room found the same thing—the best players target their errors, isolate the passage, and repeat it in context until it is reliable.
- The method: isolate the hard spot, slow it down, repeat it clean, then bring the tempo back up.
- Slow and correct beats fast and sloppy, every time.
