Theory
Yesterday you walked the progression with just the root in whole notes. Today you climb the second step of the density ramp — you add the 5th to the root and walk in half notes. You split each measure half root, half 5th. Just one more note, yet the line feels far more like walking.
Why the 5th, of all notes? The 5th is the root's steadiest partner. If the root is home, the 5th is the house next door — put it over any chord and it stays rock-solid. That's why in walking, the root-5th (R-5) is the very first skeleton of skeletons you learn. Today's rule is the same as yesterday's — beat 1 of every measure must land on the root, and on beat 3 you build a bridge to the 5th.
The fretboard has one very handy rule. The 5th sits one string up and two frets up from the root. For F7, from the root F (4th string, 1st fret), the 5th C is the 3rd string, 3rd fret; for Bb7, from the root Bb (3rd string, 1st fret), the 5th F is the 2nd string, 3rd fret; for C7, from the root C (3rd string, 3rd fret), the 5th G is the 2nd string, 5th fret. The hand shape is the same for all three chords, right?
First, grab F7's root and 5th.
▶ 4-string. The root F (4th string, 1st fret) and the 5th C (3rd string, 3rd fret). One string up, two frets up.
▶ 5-string. The positions are the same as on a 4-string. Rest your hand over the low B.
Even on a 5-string, the R-5 hand shape is the same as on a 4-string. Thanks to the low B string, you can later press the 5th in a lower octave too. Today, focus on burning the one string up, two frets up rule into your hands.
See it
Now take in the three chords' root-5th and walk the progression in half notes. First check Bb7's R-5 hand shape. It's the F7 shape moved one string over, so there's nothing new to memorize. Every example comes in both a 4-string and a 5-string version.
▶ 4-string. The root Bb (3rd string, 1st fret) and the 5th F (2nd string, 3rd fret) — the F7 shape moved one string up.
▶ 5-string. The positions are the same as on a 4-string. Rest your hand over the low B.
Now walk the progression as a half-note R-5 line. In each measure, split the root (beats 1-2) and the 5th (beats 3-4) half and half. Just keep beat 1 always on the root.
▶ BPM 72, 4-string. In each measure, R (beats 1-2) → 5 (beats 3-4), half and half. It's the R-5 line of F7-Bb7-F7-C7.
▶ BPM 72, 5-string. Same notes and positions as the 4-string. Rest your hand over the low B.
Today's practice
0–10 min · Warm-up Walk yesterday's root line once at BPM 70. Bring the root-landing feel back to your fingertips.
10–20 min · Brain training Check the three chords' R-5 hand shapes on the fretboard with your fingertips. Get to where you can picture the one string up, two frets up rule with your eyes closed. With the prep example below, walk just F7's R-5 slowly.
▶ BPM 66, 4-string. Repeat just F7's R-5 for two measures. Move between the two notes a half measure at a time, with room to spare.
▶ BPM 66, 5-string. Same notes and positions as the 4-string. Rest your hand over the low B.
20–40 min · Real play (today's product) Repeat the R-5 line above at BPM 72. Half root, half 5th per measure. Make the beat-1 root and the beat-3 5th ring at the same, even volume. Learn it on a 4-string, then confirm on a 5-string.
40–50 min · Record/feedback Record 30 seconds and listen for whether the 5th is as clear as the root. If the 5th gets buried, beat 3 goes fuzzy, so pluck both notes with the same strength.
Done when: you can walk the F7-Bb7-F7-C7 progression as an R-5 half-note line at BPM 72, landing exactly on the beat-1 root and beat-3 5th, on both a 4-string and a 5-string.
- The 5th is too quiet. It's easy to pluck the familiar root hard and touch the 5th softly. Both notes must ring at the same volume for the line to stay balanced.
▶ 4-string. C7's root C (3rd string, 3rd fret) and 5th G (2nd string, 5th fret). Here too it's one string up, two frets up.
▶ 5-string. The positions are the same as on a 4-string. You can drop to the low B to find a lower 5th too.
- You move on early at beat 2. The root must ring fully through beat 3. If you jump to the 5th too soon, the measure wobbles.
- You hunt for the shape each time. R-5 is the same shape for all three chords. Move the shape you grabbed once as a whole.
- Neglecting the 5-string low B. If you brush B while focused on the 5th, the low end leaks. Always keep the unused B covered.
