Theory
It's the final day of the week. On Monday even one "chka" felt foreign; today you finish a groove where root and ghost alternate and bounce. The dead note, the boom-chka, and the room are all in your hands now. All that's left is to tie the three into one groove and capture it as sound.
Today's piece is the root + ghost bounce. Boom the open E root as an eighth, chka the 3rd-string ghost as an eighth, and roll them alternating through the whole bar. When boom-chka-boom-chka runs on without a break, the groove keeps bouncing forward. Every feel you learned this week is packed into this one bar.
The key is a steady flow. The eight eighths have to be even for the bounce to stay smooth. Boom clear, chka a touch softer, unplayed strings quiet — keep just those three and the groove comes alive. Turn one bar over without a wobble at BPM 80.
The recording just needs to be an honest take, not a perfect one. Play Monday's single "chka" beside today's groove, and a week's growth rings out clearly. That sound is Week 5's diploma. On a 5-string finish it the same way while resting the low B.
See it
Today's visual is the week's one finished piece. Lock the root + ghost bounce on 4- and 5-string. The boom, chka, and room you learned this week are all inside this one bar.
Alternate the open E root and the ghost ("chka") as eighths. One bar of a bouncing groove.
▶ BPM 80. Alternate root (boom) and ghost (chka). Rest the left hand lightly on the ghost, no pitch. This filler makes the groove bounce. On a 5-string keep muting the low B.
▶ 5-string. Same notes and spots as the 4-string. Cover the low B with the thumb so it doesn't leak through the whole bar.
Today's practice
0–10 min · Warm-up Lightly review this week's boom-chka and room at BPM 70 to loosen up. Check the dry "chka" comes out well.
10–20 min · Brain training Retrace very slowly whether the ghost lands on its exact spot. Check whether boom and chka split evenly as eighths.
20–40 min · Real play (the Week 5 piece) Repeat the root + ghost bounce at BPM 80. The goal is to keep turning one bar over without a wobble. Learn it on the 4-string, then confirm on the 5-string.
40–50 min · Record (the graduation take) Record the root + ghost bounce. Listen with Monday's single "chka" side by side, and keep this week's finish.
Done when: you can finish a bouncing groove alternating root and ghost at BPM 80, and keep a recording on both 4- and 5-string. (Week 5 complete!)
- Chka covering the boom. If the ghost is bigger than the root, the bounce gets heavy. Keep the chka a touch softer.
- Uneven eighths. If the boom-chka gaps spread, the bounce disappears. Line up all eight exactly to the metronome.
- Rushing the tempo. A wobbly BPM 80 is no use. Even first, slow if needed.
- Neglecting low B (5-string). Cover the unused low B with the thumb through the whole bar.
