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.
Third step of the 16th-note density ladder (Stage 2 in approach.md §5). Four consecutive 16ths is the first place sustained runs appear between the feet—the endurance cost is real, and the weak foot will fatigue first. R&L is explicit that “fours” are difficult when leading with the weak foot and that avoiding them is the wrong response; the sheet reflects that by giving the weak-foot lead its own core slot.
Each Warm-Up in this chapter is written with several footing variants (alternating, doubles, and so on). Pick one variant per session and hold it for the 1-minute clean pass. Rotate variants across sessions—do not attempt every variant every day.
The bpm defaults come from the 16th-note beats row of approach.md §4 (start 50 bpm, target ~110 bpm). If the weak-foot lead cannot hold 50 bpm cleanly, drop lower until it can—that is your real starting bpm.
| Ex. | Section | Role | Start | Target |
|---|---|---|---|---|
| 1 | Warm-Ups | Four-note groups, alternating footing | 50 bpm | 110 bpm |
| 1 (weak-lead) | Warm-Ups | Same exercise, leading with the weak foot | 40 bpm | 100 bpm |
| 3 | Warm-Ups | Four-note groups, doubles footing | 50 bpm | 110 bpm |
| 9 | Beats | First beat with sustained four-16th runs | 50 bpm | 110 bpm |
| 12 | Beats | Sustained four-16th runs, different placement | 50 bpm | 110 bpm |
| Ex. | Section | Role | Start | Target |
|---|---|---|---|---|
| 5 | Warm-Ups | Four-note groups with accent | 50 bpm | 110 bpm |
| 7 | Warm-Ups | Four-note groups with accent | 50 bpm | 110 bpm |
| 17 | Beats | Funkier beat (R&L flags 17–18 as funky) | 50 bpm | 110 bpm |
| 23 | Fills | One-measure fill | 50 bpm | 110 bpm |
| 26 | Fills | One-measure fill | 50 bpm | 110 bpm |
Warm-Ups 2, 4, 6, 8 are alternate-footing pairs to their odd-numbered neighbours; touch them once the core Warm-Ups are stable. Beats 13–16 and 18–22 are groove variants; Fills 24–30 are one-measure fills. Fill 31 combines two-, three- and four-consecutive-note patterns and is worth a look once the earlier chapters are solid—treat it as a phrasing study rather than a daily drill.
Log this chapter’s work with the exercise number prefixed by 4.—for example 4.9 60 bpm 5 min fail weak-foot. See approach.md §8.
