The protocol
- Choose a 1–2 bar fragment, not a whole solo.
- Establish clean BPM (your “floor”).
- Do 3–5 passes at floor.
- Jump +4 to +8 BPM for 2–4 passes.
- Return to floor and check that it still feels easy.
- Stop the item while form is still good. Rotate to another skill.
This mirrors how motor skills consolidate: accurate repetition near the edge, not chaos past the edge. Session recipe: 1-bar metronome protocol. Background: deliberate practice and distributed practice.
