Turn a labelled error into the right five-minute drill.
The rule
pass: right drill in 3/4
Three rows of problem categories (pitch / timing / breath) crossed with three candidate drills (single-note match / pulse-clap / silent-hiss). The diagonal — the drill that actually targets each category — is emerald. The off-diagonal grey cells are the failure mode: choosing a useful drill that won’t fix thiserror. Drills aren’t interchangeable.
Hear it first
Three quick scenarios. Each names a diagnosed miss; you decide what drill you’d run next. Notice that the obviously-wrong picks are often still good drills — they’re just targeting the wrong system.
When to use this skill.Right after self-diagnosis tags a category, before you launch into another take. Untrained practice loops on “do it again” with no targeted intervention; trained practice picks a 5-minute drill that addresses the exact failure mode and then re-tries. A good rescue choice can collapse a half-hour of frustration into a single focused exercise.
Why specificity matters more than effort.Running single-note-match for an hour will not fix a timing drift — the audio-motor loop being trained is different. Pulse-clap won’t fix a flat high note. The mastery bar is 3 of 4 because the cost of a wrong rescue is high: you spend 5 minutes on the wrong system and come back to the same problem.
Why this is the curriculum capstone. Self-diagnosis names the error, rescue-drill-selection picks the cure. Together they close the loop: you can now take any failed phrase from any song and convert it into the next thing to practice — without a teacher in the room.
