Theory
Yesterday you glued the swing quarter-note feel into your hands. From today you walk the real 12-bar F blues. A month ago you could barely land a root on a single chord, and now you're walking half of a twelve-bar tune. First, let's open the whole map — | F7 | Bb7 | F7 | F7 | (bars 1–4), | Bb7 | Bb7 | F7 | F7 | (bars 5–8), | C7 | Bb7 | F7 | C7 | (bars 9–12).
Twelve boxes is the length of a blues. But there's no need to be scared — look closely and there are only three chords (F7, Bb7, C7), and today's first eight bars have no C7 at all. You only move between two homes, F7 and Bb7. You've walked with these two chords all through the last three weeks, so today's path is one you already know.
The walking rule is the same. Land on the chord on beat 1, bridge to the next chord on beat 4. Place an approach note on each bar's beat 4 and slide into the next bar's beat 1. Today you use three bridges — B (a half step above) into Bb, E (a half step below) into F, and when the same chord continues, the chord tone b7 or the lower approach A to carry on naturally. Just check whether every beat 4 calls the next beat 1 and the eight bars link into one.
First, see today's two homes, the F and Bb roots, side by side on the fretboard.
▶ 4-string. The first half's two landings — F (4th string, fret 1) and Bb (3rd string, fret 1).
▶ 5-string. Same positions as the 4-string. You can also grab a lower root on the low B.
See it
Now walk the whole first eight bars. Bars 1–4 are F7-Bb7-F7-F7, bars 5–8 are Bb7-Bb7-F7-F7. Walk each bar with R-3-5, then place a bridge on beat 4. Listen for the eight bars linking as one flow without breaking. Every example comes in both 4- and 5-string versions.
▶ BPM 80, 4-string. Beat-4 B in bars 1 and 4, beat-4 E in bars 2 and 6, beat-4 A in bar 5 are the bridges. Bars 3 and 7 continue on the same F7, so they walk to the chord tone b7.
▶ BPM 80, 5-string. Same notes and positions as the 4-string. Keep the low B covered.
Today's practice
0–10 min · Warm-up Walk yesterday's F7 swing walk once at BPM 72. Bring the swing quarter-note feel back to your fingertips.
10–20 min · Brain training Before walking the whole first half in one go, take just bars 1–4 at a slow BPM 70 with the prep below. Check that the seams between bars are smooth.
▶ BPM 70, 4-string. Bars 1–4 only, slow. Check that the beat-4 bridges (B, E, B) slide into the next beat 1.
▶ BPM 70, 5-string. Same notes and positions as the 4-string.
20–40 min · Real play Walk the first eight bars above from start to finish at BPM 80. Don't stop midway; if a bar trips you up, fix just that bar slowly, then link it back in. Learn it on 4-string, then confirm on 5-string.
40–50 min · Record / feedback Record the eight bars for 30 seconds and listen for whether the chord changes (bar 1→2, bar 4→5) feel natural. Note today's reached BPM — it's tomorrow's starting point for the second half.
Done when: you can walk the F blues first half (eight bars of F7 and Bb7) at BPM 80 in swing quarters, landing every beat 1 and bridging every beat 4 without breaks, on both 4- and 5-string.
- Repeated F7 bars feel dull. When the same chord continues, as in bars 3 and 7, add a touch of color with the chord tone b7 (3rd string, fret 6). You don't have to walk it the same way every time.
- Your hand lags on chord changes. When the position shifts, as in bar 4→5 or bar 8, prepare the next hand shape the instant you place the beat-4 bridge. The bridge is the signal to move your hand early.
Sort out Bb7's chord tones too. Seeing where R-3-5-b7 sit from the Bb root makes bars 5 and 6 easier.
▶ 4-string. Bb7's R (3rd string, fret 1), 3 (2nd string, open), 5 (2nd string, fret 3), and b7 (1st string, fret 1).
▶ 5-string. Same positions as the 4-string. Keep the low B covered.
- Walking half of it is a big deal. Once you can link eight bars, the remaining four just add the same principle plus one more chord (C7). Getting this far today already puts most of the 12 bars in your hands.
