Theory
Yesterday you enclosed the root. Today you move the enclosure target to the chord's third. The third is the color note that decides whether the chord is bright (major) or dark (minor). If the root is the home address, the third is the face of that home. When you enclose the face, the chord's color comes alive most vividly.
The third of the home chord Fmaj7 in the key of F is A. Let's enclose this A — pass through the half-step above, Bb, and the half-step below, G#, then land on A. When you wrap and settle onto the third, you hear a bright, clear color unlike landing on the root.
The order is always the same — above → below → land. The third is the most beloved enclosure target in jazz walking. Aiming only at the root makes the walk monotonous, but wrapping and landing on the third gives the line an expression. Today you complete a wrap-and-land with the third as your target.
First, see the three notes that wrap the third A — the upper Bb, the lower G#, and the landing third A — on the fretboard.
▶ 4-string. Upper Bb (4th string, fret 6), lower G# (4th string, fret 4), landing third A (4th string, fret 5). The green dot is the landing target.
▶ 5-string. Same positions as the 4-string. Keep the low B covered.
See it
Now lay the third enclosure onto time and walk it. Walk the upper Bb → lower G# → landing A one beat each, and on the last beat 4 continue to Fmaj7's 5th, C. Feel whether the color of settling onto the wrapped third sounds deep. Each example comes in both 4- and 5-string versions.
▶ BPM 80, 4-string. Beat 1 Bb → beat 2 G# → beat 3 land on A → beat 4 C (5th). After squeezing from above and below, you settle firmly onto the third A.
▶ BPM 80, 5-string. Same notes and positions as the 4-string. You can lay a heavier low end with the low B.
Today's practice
0–10 min · Warm-up Walk yesterday's root enclosure once at BPM 72 to bring back the feel of wrapping and landing.
10–20 min · Brain training Press the third enclosure with the prep example below at a slow swing-quarter BPM 60. Check by ear that the upper Bb and lower G# squeeze exactly onto the third A.
▶ BPM 60, 4-string. The third enclosure, slowly. Pass through the upper Bb and lower G# and land exactly on A.
▶ BPM 60, 5-string. Same notes and positions as the 4-string.
20–40 min · Real play Repeat the third enclosure above at BPM 80. See whether the landing A lights up the chord's color brightly. Learn it on 4-string, then check on 5-string too.
40–50 min · Record / feedback Record 30 seconds and listen for whether the color of settling onto the third A is clear. If the color is blurry, try cutting the two notes above and below a little shorter.
Done when: you can wrap the third A with a half-step above (Bb) and below (G#) and land firmly on the third in swing quarters on both 4- and 5-string.
- You press the third heavily, like a root. The third is a color-giving note, so hitting it too hard makes it sound like a root. Keep the landing clear but a touch lighter than the root, and press it as if singing.
- You press the lower neighbor G# vaguely. G# (4th string, fret 4) is a leading tone that rises a half-step into A. You must press it precisely for the pull upward to come alive.
Keep today's wrapped third, the single point A, in your eye. If the root is the home address, this third is the chord's expression.
▶ 4-string. Today's landing third, A (4th string, fret 5). This one green dot decides the chord's color.
▶ 5-string. Same position as the 4-string. You can also gauge a lower spot with the low B.
- On day three, you've started handling color. Now that you can enclose the third as well as the root, your walk gains an expression. Tomorrow you'll weave this enclosure into an actual walking bar and build week 6's finished piece.
