Month 1 — The right-hand groove engine: motor, ghosts, accents, and a first one-chord jam · Week 1

Starting the 16th-note motor — splitting one beat into four

about 50 min

Theory

If your funk never quite grooves, the culprit is usually not your left-hand chords — it's the right hand. Eighty percent of funk is right-hand rhythm, and its beating heart is the 16th-note motor.

16ths split one beat into four pieces. Count aloud: "1-e-&-a." Four per beat, sixteen across four beats — hence "16th." Over that grid your right hand swings, alternating down (moving down) and up (coming back), so down-up-down-up falls naturally onto the sixteenths.

The single most important feeling is this: the right hand never stops, like a sewing machine or a pendulum. Whether you actually strike a string or not, it's your wrist — not your forearm — that keeps swinging up and down. That swing is the engine of the groove.

At first your hand will feel stiff and the beat will smear — that's completely normal. Today isn't about a clean sound; it's about laying your left fingers lightly across the strings to mute them and burning in the "chika-chika" swing. Once this one motor is in place, every funk rhythm you learn later just rides on top of it. Even if today ends with no sound at all — just a swinging hand — that counts as a success. That hand-that-never-stops is the real strength that will carry you through the next two months.

See it

Today's stage isn't sound — it's the swing. Both examples below stay muted (left fingers resting on the strings), so you watch only the right-hand 16ths. (The plain, colorless notes are deliberate — right now rhythm, not pitch, is the star.)

Example 1 — 16th motor (1 bar). Sixteen sixteenth-notes splitting each beat into four. Down-up-down-up, never resting.

= 651
16th-note muted motor (1 bar)

BPM 65. Left hand lightly muted, right hand from the wrist only. Repeat 4×, counting "chika-chika" aloud. Aim for even swing over clean sound.

Example 2 — 2-bar endurance. Keep the hand moving even as the bar turns over. There must be no moment of stopping between bar 1 and bar 2.

= 6512
16th-note muted motor (2 bars, endurance)

BPM 65. Treat two bars as one breath. If the swing breaks at the bar line, it fails. Once easy, stretch to four bars.

Today's practice

0–10 min · Warm-up Metronome BPM 60–70. With your left fingers resting to mute the strings, mechanically repeat 16th empty-picking / muted scratching anywhere. Focus on the swing, not the sound.

10–20 min · Brain training (today's target = splitting the beat) To the metronome, count "1-e-&-a" aloud while swinging your hand. Sync mouth and hand so one beat divides exactly into four.

20–40 min · Real groove (Examples 1·2 / BPM 65) Repeat Example 1 (1-bar motor) 4× at BPM 65 → once easy, stretch to Example 2 (2-bar endurance). The key is that the hand never stops as the bar turns.

40–50 min · Record & reflect (recommended) Record 30 seconds and check: are down/up even in volume / did the beat drag / did the hand ever stop mid-way?

Done when: you can swing four beats of muted 16ths without the hand stopping, and count "1-e-&-a" to split each beat into four.

  • Strumming from the forearm. Playing 16ths with big muscles tires you fast and smears the beat. A preview of tomorrow's wrist snap — keep the arm as still as possible.
  • The habit of stopping. If you only move when you strike, the beat drifts. The hand swings even with no note.
  • Greed for speed. Even at 60–70 beats smeared at 100 — far more pro. Speed follows on its own later.
  • Tension in the shoulder. Tension makes the swing stiff. Drop your shoulder and arm loose before you start.
