Session role: focus and application blocks. 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 (one Ch. 2 exercise) → ~5–6 min application (one Ch. 2 beat or fill) → ~2 min cool-down. Full detail in approach.md §6.
This is the first chapter of the 16th-note density ladder (Stage 2 in approach.md §5). Two consecutive 16ths between the feet is the smallest unit that forces the weak foot into the same job as the strong foot. R&L notes that although two-note ideas can be played with one foot, the ability to play two evenly and powerfully between the feet is what has to be developed here—that framing is exactly what this sheet trains.
Work the Warm-Ups first. They are density drills—the point is not musicality but making the two feet sound identical on the doubled 16ths. Only once the Warm-Ups feel even should you move to the Beats, which put the doubled 16ths inside a groove. Fills are the last thing to touch and stay mostly reference—one or two is enough.
Kit-setup note (before your first Beat). The Ch. 2 Beats introduce the hi-hat while both feet stay on the bass drum pedals—the left foot is on BD II playing the doubled 16ths. See approach.md §3.3 for the dry-closed clutch convention that lets you sound closed hi-hat (matching R&L’s x notation) without any left-foot input. The manual does not ask you to alternate the left foot between BD II and the hi-hat pedal.
The 36 exercises are not a checklist. Each session’s focus block works one exercise, not all five in the Core—rotate through them across sessions so all five get worked over time. The core list below is where most of your focus and application time goes. The rotation list adds variety when the core feels stale or when a specific pattern is coming up in your listening. The reference exercises (Beats Ex. 2.13–2.20 and most Fills) are R&L’s raw material; treat them as discretionary.
The bpm defaults below come from the 16th-note beats row of approach.md §4: start 50 bpm, target ~110 bpm. Warm-Ups start at the same 50 bpm because the coordination cost is what makes them hard, not the speed.
Increment differs by exercise type. Per approach.md §4, the Warm-Ups (Ex. 2.1 and Ex. 2.3) are feet-only and advance at +4 bpm per two-pass advancement; the Beats (Ex. 2.5, Ex. 2.7 and Ex. 2.10) advance at +2 bpm. Both ladders from 50 land on the 82 bpm Ch. 3 unlock exactly—no rounding needed. See “Moving on to Ch. 3” below.
Your first Ch. 2 session is your first session after Stage 2 unlocks (Ex. 1.1, Ex. 1.10 and Ex. 1.11 all reached their 90 bpm unlock—see chapter-01.md “Moving on to Stage 2”). Session shape changes at the same moment: from “Ch. 1 is the whole session” to the three-block template from approach.md §6—warm-up (Ch. 1), focus (Ch. 2), application (Ch. 2), cool-down.
This concrete walkthrough is what the session runbook in approach.md §7 looks like when applied to Ch. 2 for the first time; on later sessions the same shape applies with the bpm coming from your tracking document rather than from this sheet.
2.1 <bpm> bpm 15 min <verdict> <note>. Update the working state per approach.md §8; on this first-ever session that means last pass bpm ← ceiling and current bpm ← ceiling directly (waiting for confirmation next time).2.5 <bpm> bpm 5 min <verdict> <note>. Update the working state per approach.md §8; on this first-ever session that means last pass bpm ← ceiling and current bpm ← ceiling directly.That is a complete first Ch. 2 session. You have not touched Ex. 2.3, Ex. 2.7 or Ex. 2.10—those come in later sessions as you rotate through the Core.
On your second session, look up the bpm and verdict for each exercise from session one. The advancement rule (approach.md §4) is two consecutive pass sessions at the same bpm before you raise the metronome—and it applies per exercise, so Ex. 2.1 and Ex. 2.5 advance on their own two-pass counts. Options for session two:
pass at their session-one bpm, a second pass earns the raise (+4 for Ex. 2.1, +2 for Ex. 2.5) on session three.Both are valid. Consistency beats coverage in the first fortnight—if you are unsure, repeat the same pair until each Core exercise has two passes on the board, then rotate.
The Ch. 2 Core has five exercises but each session’s focus block holds one (two on longer days) and each session’s application block holds one. That means five exercises need to share your focus and application time across a training week. A workable pattern for the first two or three weeks, at roughly five sessions a week:
That is one session per Warm-Up every second day and one session per Beat every third day—enough to accumulate two-pass advancements on each without any single exercise sitting stale for a week. Adjust to fit your schedule; the mechanical loop from approach.md §7 applies unchanged regardless of which Core exercise is in the block.
Worked advancement example, Ex. 2.1 (Warm-Up, +4 bpm ladder). Session A pass at 50 bpm; session B (next Ex. 2.1 session) pass at 50 → raise; session C raise to 54, pass; session D pass at 54 → raise; session E raise to 58, pass… The two passes accrue across sessions on the days you actually work Ex. 2.1, not back-to-back days on the calendar—if Ex. 2.1 lands every second day, the two passes are two days apart. Per approach.md §4 that is if anything a stronger confirmation than a same-day repeat.
Worked advancement example, Ex. 2.10 (Beat, +2 bpm ladder). Same shape, but each raise is +2 bpm instead of +4. Session A pass at 50; session B (next Ex. 2.10 session) pass at 50 → raise; session C raise to 52, pass; session D pass at 52 → raise; session E raise to 54… The +2 ladder reaches 82 (the Ch. 3 unlock bpm) in 16 increments; assume roughly one advancement per week per exercise once things are stable, so plan for Ex. 2.10 to reach 82 over three-to-four months of steady work.
When a probe fails with time still on the clock. Drop the metronome back to the last cleanly-passed rung—the session ceiling, which on a first probe up from your current bpm is the current bpm itself—and use the remaining minutes to reinforce it. Do not grind at the failing bpm. Sustained reps above the ceiling groove tension and uneven mechanics without moving the ceiling; the ceiling has already been recorded for this session, and quality reps at the rung below it set up next session’s probe. See approach.md §7 focus block step 4 for the general rule.
Your focus and application pool for this chapter. Pick one exercise for the focus block and one Beat for the application block each session, rotating across sessions so all five get worked over time. Concretely: for the chosen exercise, look up your current bpm in the tracking document (or use the starting bpm for the first time), set the metronome, set a timer for the block minutes, play unbroken until the timer stops, log a verdict per the clean-pass rule (approach.md §4), then move on to the next block.
| Ex. | Section | Role | Start | Unlock | Target | Increment |
|---|---|---|---|---|---|---|
| 2.1 | Warm-Ups | Doubled 16ths on beat + e, strong-foot lead | 50 bpm | 110 bpm | +4 bpm | |
| 2.3 | Warm-Ups | Doubled 16ths on & + a, strong-foot lead | 50 bpm | 110 bpm | +4 bpm | |
| 2.5 | Beats | Rock beat, doubled 16ths on 3 + 3e, strong-foot lead | 50 bpm | 110 bpm | +2 bpm | |
| 2.7 | Beats | Rock beat, doubled 16ths on 3& + 3a plus single strong-foot kicks on 1, 1& and 3, strong-foot lead | 50 bpm | 110 bpm | +2 bpm | |
| 2.10 | Beats | Rock beat, doubled 16ths on 2& + 2a and 4& + 4a plus single strong-foot kicks on 1& and 3&, strong-foot lead | 50 bpm | 82 bpm | 110 bpm | +2 bpm |
Why these five? R&L Ch. 2 has 36 exercises but most are variations on the doubled-16th idea. All five Core exercises use strong-foot lead; they differ on where in the beat the two 16ths land (front vs. back) and, for the Beats, how many kicks per bar total. Warm-Ups Ex. 2.1 and Ex. 2.3 isolate the foot pattern before hands enter—Ex. 2.1 on beat + e (front of beat), Ex. 2.3 on & + a (back), each repeated every beat. Beats Ex. 2.5, Ex. 2.7 and Ex. 2.10 carry the same front-vs-back axis inside a rock groove (hi-hat 8ths, snare on 2 and 4) and add a density ladder: Ex. 2.5 is 3 kicks/bar (doubled on beat 3 + 3e, front), Ex. 2.7 is 5 kicks/bar (doubled on 3& + 3a plus singles on 1, 1& and 3, back), Ex. 2.10 is 6 kicks/bar (doubled on 2& + 2a and 4& + 4a plus singles on 1& and 3&, back on beats 2 and 4). Ex. 2.10 sits at both extremes—highest density, latest placement—which is why it gates Ch. 3 (see “Moving on to Ch. 3”).
Once the Core is stable (say, two weeks of consistent pass verdicts across Ex. 2.1, Ex. 2.3, Ex. 2.5, Ex. 2.7 and Ex. 2.10), you can start dropping in a Rotation exercise. Two ways to use it: swap it in for a Core exercise on a given session (so the total block count stays the same), or add it as a fourth block if you have session time to spare. Do not stack more than one Rotation exercise on the same day; the Core is the main path.
| Ex. | Section | Role | Start | Target | Increment |
|---|---|---|---|---|---|
| 2.2 | Warm-Ups | Doubled 16ths on e + & (middle of beat), weak-foot lead | 50 bpm | 110 bpm | +4 bpm |
| 2.4 | Warm-Ups | Dotted 8th + 16th per beat; doubled 16ths across the beat boundary, strong-foot lead | 50 bpm | 110 bpm | +4 bpm |
| 2.12 | Beats | Rock beat, three doubled-16th events per bar (1& + 1a, 2& + 2a, 3& + 3a) plus single strong-foot kicks on 1 and 4&, strong-foot lead | 50 bpm | 110 bpm | +2 bpm |
| 2.21 | Fills | One-measure fill with doubled 16ths | 50 bpm | 110 bpm | +2 bpm |
| 2.24 | Fills | One-measure fill with doubled 16ths | 50 bpm | 110 bpm | +2 bpm |
Cadence. Aim for each Rotation exercise to get worked once every couple of weeks or so when time allows—about one Rotation slot per practice week at the ~5-days-per-week baseline. That is a target, not a rule: skip Rotation entirely on short days, and a missed fortnight is not a debt. The advancement rule still applies—two consecutive pass sessions at the same bpm earn the raise—but the two sessions accrue across weeks rather than back-to-back days.
Beats Ex. 2.13–2.20 and Fills Ex. 2.22–2.36 are reference material. R&L flags Beats Ex. 2.13–2.18 as harder and says you can come back to them later; Beats Ex. 2.16–2.18 use syncopated snare rhythms; Beats Ex. 2.19–2.20 are two-bar phrases meant as combining fodder. Fills Ex. 2.21–2.30 are one-measure ideas, Fill Ex. 2.31 is a two-bar phrase with a short fill, Fills Ex. 2.32–2.33 are phrases containing a one-bar fill and Fill Ex. 2.34 is longer than a measure. Dip into these when you want variety or when your ear picks one out—do not treat them as a checklist. If you never play them, that is fine.
Ch. 3 (three consecutive 16ths between the feet—see approach.md §5) unlocks when Ex. 2.10 reaches its unlock bpm of 82 bpm—two consecutive pass sessions at 82 bpm on Ex. 2.10, per the advancement rule in approach.md §4. Ex. 2.10 is a Beat and advances at +2 bpm; the +2 ladder from 50 lands on 50, 52, 54, …, 80, 82—so 82 is on the ladder and no rounding is needed.
Only one gate exercise, not three. Within-stage transitions inside the 16th-note density ladder (Ch. 2 → 3 → 4 → 5) are quantitative—denser runs of the same subdivision—rather than qualitative, so one checkpoint is enough per approach.md §5 (unlock scheme, rule 2). Ex. 2.10 is the gate because it has the highest doubled-16th density per bar of any Ch. 2 Core exercise—doubled 16ths on both 2& + 2a and 4& + 4a, i.e. twice per bar versus once per bar in Ex. 2.5 and Ex. 2.7.
Two things this rule is not:
When Ex. 2.10 reaches 82 bpm (two consecutive passes at 82), open chapter-03.md and add Ch. 3 to your active list per the tracking-document header format (approach.md §8). What happens to Ch. 2 at that moment is a choice, not a rule:
If unsure, take the common path. Ch. 2 material is not lost by aging out; the doubled-16th pattern is present in every subsequent Stage 2 chapter and stays in play through the density ladder.
Log this chapter’s work in your tracking document (approach.md §8) with the exercise number prefixed by 2.—for example 2.5 56 bpm 5 min pass even, or with a short trailing comment: 2.5 56 bpm 5 min pass even, weak foot solid on the sustained bar. See approach.md §8 for the full tag-plus-optional-prose convention. Log only what you actually practised; there is no obligation to touch every exercise in every session.
