Theory
At last, the final day of Week 5, the day you complete ii-V-I into one. The three pieces you prepared over the past three days — the three chords' tones (D1), the ii→V seam (D2), the V→I resolution (D3) — you now link into a single three-bar walk. Gm7 → C7 → Fmaj7, walking jazz's road home from start to finish.
The structure of the deliverable is simple. One chord per bar — beats 1, 2, and 3 walk that chord's tones, and beat 4 is the bridge to the next chord. Bar 1's Gm7 beat 4 is Db, aiming at C; bar 2's C7 beat 4 is E, aiming at F. And in bar 3 you arrive home at Fmaj7 and rest easy. The two bridges thread three chords into one walk.
Walk it at BPM 85 in swing quarter notes. Beat 1 of every bar lands squarely on the root, and beat 4 crosses smoothly to the next chord. Beat 1 lands, beat 4 bridges — this principle you've drilled all month and a half now comes together over ii-V-I, the core progression of jazz. Start slow, and once it settles into your body, raise the speed bit by bit.
First, see the landmarks of the three-bar walk — the three roots (G·C·F) and the two bridges (Db·E) — on the fretboard.
▶ 4-string. The three roots G (4th string, fret 3), C (3rd string, fret 3), F (4th string, fret 1), and the two bridges Db (3rd string, fret 4), E (3rd string, fret 7).
▶ 5-string. Same positions as the 4-string. You can also gauge lower roots on the low B.

At last, this week's deliverable, the three-bar ii-V-I walk. Link Gm7-C7-Fmaj7 with the two bridges and walk it in one go, as if heading home. Every example comes in both 4- and 5-string versions.
▶ BPM 85, 4-string. Gm7 (bar 1) → C7 (bar 2) → Fmaj7 (bar 3). Bar 1's beat-4 Db approaches C, bar 2's beat-4 E approaches F. At V→I you arrive home.
▶ BPM 85, 5-string. Same notes and positions as the 4-string. You can also add a heavier low end on the low B.
Today's practice
0–10 min · Warm-up Walk yesterday's C7→Fmaj7 resolution once at BPM 72 to bring the feel of the two bridges (Db·E) back to your fingertips.
10–20 min · Brain training With the prep below, press the three-bar walk as slow swing quarters at BPM 65 and set the chord changes slowly. Check whether the two bridges lead naturally into the next bar's root.
▶ BPM 65, 4-string. The three bars slowly. Set the two seams squarely: bar 1 beat-4 Db → bar 2 C, and bar 2 beat-4 E → bar 3 F.
▶ BPM 65, 5-string. Same notes and positions as the 4-string.
20–40 min · Real play Repeat the ii-V-I walk above as a three-bar cycle at BPM 85. Watch whether the three chords connect seamlessly through the two bridges. Learn it on 4-string, then confirm the same flow on 5-string.
40–50 min · Record / graduation At last, recording. At a comfortable tempo, record the three ii-V-I bars two or three times without stopping, and keep the best take as your first ii-V-I walk. Save both 4- and 5-string and Week 5 is complete.
Done when: you can walk and record the three-bar Gm7-C7-Fmaj7 ii-V-I walk, linked by the two approach notes (Db·E), in swing quarters on both 4- and 5-string, as if heading home. — Weekly deliverable: a recording of your first ii-V-I walking bass. (Week 5 complete!)
- Your hand tangles in bar 2's C7. You dip briefly to the lower string with C7's 5th G (4th string, fret 3), then return to b7 Bb (3rd string, fret 1). Learn this hand shift at a slow tempo ahead of time and real play gets easier.
- You rush the landing after a bridge. Off the beat-4 bridge (Db·E), it's easy to get excited and pull the next beat 1 early. Both bridges are a single half-step, so don't hurry — land exactly on the beat.
Look at this week's stars, the two bridges Db and E, at a glance. These two approach notes are the key that threaded three chords into one.
▶ 4-string. Bar 1's Gm7 bridge Db (3rd string, fret 4) and bar 2's C7 bridge E (3rd string, fret 7), the two approach notes.
▶ 5-string. Same positions as the 4-string. Keep the low B covered.
- Give yourself big credit for Week 5. You started with three chords' tones, linked them with approach notes, and now you've walked ii-V-I, the core progression of jazz, in swing quarters and even recorded it. That's a big step. From next week you'll walk this ii-V-I over more keys and longer progressions, expanding it into real jazz walking.
