Theory
Today you use yesterday's clean ghost ("chick") as groove material. Today's goal is thumb-ghost-pop — that is, joining the three strikes thumb (boom)-chick-pop (snap) into one flow. These three beats are the heart of this week's groove.
Picture the order in sound. Thumb the root E (4th string) for "boom," immediately a left-hand ghost — "chick" on the 3rd string — then the index finger pops the octave (2nd string, 2nd fret) for "snap." In drum terms it's like kick-hi-hat-snare passing by in order. That one "chick" fills the gap between boom and snap, and two flat notes suddenly start to roll.
Today, don't overreach — focus only on making thumb-ghost-pop flow steadily. Put one rest after the three strikes so the hand has room to set up the next bundle. At BPM 60, spread the three strikes wide in quarters, then string them densely in eighths at BPM 65. Whether the three are evenly spaced is what counts. At first the pop tends to rush in, so widen them while counting the "chick" as its own independent strike. Once the three each hold their place, the speed comes on its own afterward.
On a 5-string, the notes and hand shape are the same as on a 4-string. Keep the low B deadened with the thumb, and once comfortable, try the same thumb-ghost-pop on a heavier low string too. Today, carve just one feel into your hand — the three strikes connecting smoothly. Once these three lock into one today, this week's groove is nearly all in place before your eyes.
See it
First, retrace the octave hand shape — the lower blue is the root E you slap with the thumb, the upper blue is the octave E you pop. The "chick" between them comes from laying the left hand on the 3rd string. After checking the shape, string slap-chick-pop wide in quarters, then densely in eighths. Each example comes in both a 4-string and a 5-string version.
▶ 4-string. Root E below (thumb), octave E above (pop). The "chick" between them comes from the 3rd string.
▶ 5-string. The hand shape is the same as on a 4-string. Keep the low B deadened with the thumb.
Example 1 — thumb-ghost-pop quarters. Spread the three strikes one beat wide each. Thumb (boom)-chick-pop (snap), then one rest.
▶ BPM 60, 4-string. Boom (T)-chick-snap (P)-rest. Check slowly that the three are evenly spaced.
▶ 5-string. Note and hand shape are the same as on a 4-string. Keep the low B deadened with the thumb.
Example 2 — thumb-ghost-pop eighths. Now densely. Put slap-chick-pop-rest twice per measure.
▶ BPM 65, 4-string. Let boom-chick-snap flow within each beat. Even faster, don't let the "chick" smear.
▶ 5-string. Same notes as the 4-string. Here too, keep the low B deadened with the thumb.
Today's practice
0–10 min · Warm-up Make the "chick" from yesterday a few times at BPM 60 to wake the hand. Check by ear again that there's no pitch.
10–20 min · Brain training Play slap-chick-pop very slowly, one strike at a time. Check one by one whether the three sounds are clearly different in character (boom, chick, snap).
20–40 min · Real play Repeat Example 1 (quarters) at BPM 60 → once the three strikes are even, move to Example 2 (eighths) at BPM 65. If the flow tangles, drop back to quarters.
40–50 min · Record/feedback Record 30 seconds and listen for whether boom-chick-snap comes through clearly in order. Note the BPM you reached today.
Done when: you can flow thumb (root)-ghost ("chick")-pop (octave) at BPM 60–65 with the three strikes evenly connected, on both a 4-string and a 5-string.
- The "chick" vanishes. Fussing only over boom and snap buries the middle ghost. Stamp the "chick" clearly as its own strike too.
- The pop rushes. If the pop slams in right after the "chick," the flow tangles. Drop to quarters and widen the spacing of the three first.
- The hand shape wobbles. If the octave shape loosens while you make the ghost, the pop misses. Keep the shape and only lay-and-lift the left hand lightly.
- Neglecting low B (5-string). As the hand gets busy, B leaks easily. Always keep B covered with the thumb.
