Skeleton sheet. This chapter has the metadata block and Core / Rotation / Reference tables but has not yet been rewritten to the shape of chapter-01.md and chapter-02.md—no first-session walkthrough, no worked advancement example, no per-exercise rationale. See chapter-template.md for the shape this sheet will take when filled, and DEVELOPMENT.md “Things to do later” for the outstanding propagation work.
Session role: focus block.
Every session opens with warm-up on the current R&L Ch. 1 exercises before you work this chapter. Baseline 30-min session: ~7–8 min warm-up (Ch. 1) → ~15 min focus (this chapter) → ~5–6 min application → ~2 min cool-down. Full detail in approach.md §6.
Fourth chapter of Stage 6 (approach.md §5). This is the triplet-feel companion to Ch. 16—where Ch. 16 drops 32nd-note doubles into a 16th-note single-bass groove, this chapter drops 16th-note-triplet doubles into an 8th-note-triplet single-bass groove. Feet only, one page, sixteen exercises.
R&L keeps the coaching short here. Balance and posture matter more than usual when the feet are the only thing moving—leaning forward or backwards shifts the weight off the pedals and changes how the doubles articulate. Start slowly and work up.
The bpm defaults come from the feet-only row of approach.md §4 (start 60 bpm, target ~120 bpm), applied to the triplet subdivision. Because 16th-note-triplet doubles are physically dense, expect the real starting bpm to be well below 60—drop until the second stroke of each double is as loud as the first.
| Ex. | Role | Start | Target |
|---|---|---|---|
| 1 | First triplet-doubles pattern | 50 bpm | 110 bpm |
| 3 | Triplet-doubles pattern variant | 50 bpm | 110 bpm |
| 7 | Denser triplet-doubles phrase | 40 bpm | 100 bpm |
| Ex. | Role | Start | Target |
|---|---|---|---|
| 5 | Triplet-doubles pattern variant | 50 bpm | 110 bpm |
| 9 | Longer triplet-doubles phrase | 40 bpm | 100 bpm |
| 13 | Displaced triplet-doubles phrase | 40 bpm | 100 bpm |
Exercises 2, 4, 6, 8, 10, 11, 12, 14, 15, 16 are further triplet-doubles patterns. Sample when the core list feels stale.
Log this chapter’s work with the exercise number prefixed by 18.—for example 18.1 50 bpm 15 min pass even-doubles. See approach.md §8.
