Theory
Day two. You widen yesterday's one bar into the song form. Connect the neo-soul signature vamp Dm9 → G13 across two bars. Bar 1 is Dm9 comping, bar 2 caps G13 with a smear fill.
G13 is a hand shape with a root on the 6th string fret 3, and b7·3·13 stacked on top. Its hand position differs from Dm9 — that move is today's gateway. When the two chords connect smoothly, the song starts to flow.
The end of bar 2 closes with the b3→3 smear fill. One line sliding over the tail of G13 ties the two bars into one. The fill opens the door to the next repeat.
▶ The G13 comping grip: 6th string fret 3 (R) with b7·3·13 stacked on top.
See it
Dm9 comping + G13 + smear fill, the two-bar form of the song to come. Lay it back in bar 1, then tint and slide in bar 2.
▶ BPM 72, swing 16. Bar 1 Dm9 laid-back comping → bar 2 G13 then b3→3 smear fill. The two bars connect like one song.
Today's practice
0–10 min · Warm-up At BPM 60, grip Dm9 and G13 alternately. Let your body memorize the move between the two shapes first.
10–20 min · Brain training (chord change) Isolate just the Dm9 → G13 move and repeat it slowly. Let your fingers prepare the next spot in advance.
20–40 min · Real two bars (BPM 72) Loop the two-bar form above. Firm up the chord change with the transition drill below, then join it. When the beat doesn't wobble at the change, the form stands.
▶ BPM 60. Move Dm9 ↔ G13 one beat each, big. Fingers plant the next spot ahead of time.
40–50 min · Recording / self-feedback (recommended) Record and listen back. Check that the two bars flow like one song without a break.
Done when: You can join the two-bar song form without a break at BPM 72, swing 16 — including the Dm9 → G13 change and the b3→3 smear fill.
Just the mistakes that show up most as you join the two bars.
▶ Isolate the smear fill and draw the b3→3→5→b7 line slowly.
- You collapse at the change. The beat wobbles easily where the chord changes. Learn the move spot into your body.
- The fill smears. Draw b3→3→5→b7 clearly, opening it like a door into the bar.
- G13's lower strings leak. Keep only the 6th string root clear and lightly mute the unused strings.
- You raise speed first. Firm up the change and fill at BPM 60, then raise to 72.
