Theory
At last, Week 8 — the final week! Eight weeks ago even one slap note was hard, and now you hold the octave, the ghost, and the pop in one hand. This week you melt the pieces you've learned into one groove and complete a graduation piece that smells of classic funk. Today, Day 1, is the first button: you lay a pop fill over an octave + ghost groove to build exactly one measure.
The skeleton of the groove is already familiar. Thumb the open E on the 4th string (R), fill the gap with a ghost, then pop the octave E at the 2nd fret of the 2nd string (8). This thumb-ghost-pop rolls like a drum's kick and snare. Today, after this groove, you top off the measure with a b3-4-5 pop fill on the 1st string.
The pop fill doesn't need to be flashy. Pop b3 (open), 4 (2nd fret), 5 (4th fret) on the G string cleanly, one by one, and the groove lifts its head a little, like singing. BPM 85 is the goal, but today start slow and first smooth the connection between groove and fill. If you rush into the fill, the beat drags, so pin each note down beat by beat.
Even on a 5-string, the hand shape is the same. Keep the low B deadened with the side of the thumb and focus only on the groove and the pop fill. On a 5-string you could also do a heavier version rooted on the low B, but today get the feel in the same E position. First mark the spots the groove and fill pass through on the fretboard — today's whole measure comes from here.
▶ 4-string. The R (E) on the 4th string and the octave 8 (E) on the 2nd string are the groove; the b3·4·5 on the G string are the pop fill.
▶ 5-string. The hand spots are the same as on a 4-string. Keep the low B deadened with the thumb.
See it
Today you complete one measure! First warm the hand with the octave + ghost groove, then lay the b3-4-5 pop fill on top. Each example comes in both a 4-string and a 5-string version.
First, the octave + ghost groove. Thumb the E on the 4th string, fill the gap with a ghost, and pop the octave E on the 2nd string.
▶ BPM 75, 4-string. The thumb-ghost-pop rolling — the skeleton of the groove.
▶ 5-string. The notes and spots are the same as on a 4-string. Keep the low B deadened with the thumb.
Now lay the pop fill over the groove. The first half is the octave groove, the second half finishes like a song with the b3-4-5 pop.
▶ BPM 85, 4-string. Front is the octave groove, back is the b3-4-5 pop fill. Today's finished single measure.
▶ 5-string. The notes and the move are the same as on a 4-string. Keep the low B deadened with the thumb.
Today's practice
0–10 min · Warm-up Shake the Week 7 pop arch lightly at BPM 50 to wake the hand. Today you'll join groove and pop into one measure.
10–20 min · Brain training Run the finished measure very slowly as below, carving into your hand the connection that crosses from groove to pop fill.
▶ BPM 60, 4-string. Very slowly. Check that the b3-4-5 fill lands in place after the octave groove.
▶ 5-string. The notes and the move are the same as on a 4-string. Keep the low B covered with the side of the thumb.
20–40 min · Real play Repeat the finished measure at BPM 85. If the fill smears, drop the tempo and revive groove and pop separately. Learn it on the 4-string, then confirm it on the 5-string too.
40–50 min · Record/feedback Record 30 seconds and listen for whether the groove and fill join smoothly. Note the BPM that felt comfortable today.
Done when: you can smoothly play the finished single measure — an octave + ghost groove topped with a b3-4-5 pop fill — at BPM 85.
Nudge the finished measure up to BPM 90 and check that the groove and fill stay alive even as it speeds up.
▶ BPM 90, 4-string. Check that the octave groove and pop fill stay clearly alive even as it speeds up a little.
▶ 5-string. The notes and the move are the same as on a 4-string. Always keep the low B deadened with the thumb.
- The fill drags. If you rush crossing from groove to fill, it drags. Pin each note down beat by beat.
- The octave is weak. The 2nd-string octave pop tends to go faint. Snap it at the same size as the thumb.
- The ghost rings. If a pitch lingers in the gap-filling ghost, it gets messy. Make only the click, with no pitch.
- Neglecting low B (5-string). Absorbed in the groove, B rings easily. Always keep B covered with the side of the thumb.
