Walking Bass Lines: How to Walk Over Blues and ii–V–I

A walking bass line moves in steady quarter notes, with a new note on almost every beat. It is the sound of jazz, swing, blues and early rock and roll. Walking looks like improvisation, but it follows a few rules: land on chord tones where the harmony needs to be clear, and use the beats in between to travel smoothly to the next chord.

The quarter-note pulse

A walking line is a carpet the whole band stands on: every quarter note needs the same length, volume and placement.

• Connect the notes. Let each note ring until the next one starts. Short, choppy quarter notes sound nervous.
• Play even dynamics. Beat 1 can be slightly stronger, but no note should jump out.
• Feel the swing. In jazz and blues the quarter notes themselves are straight, but the drummer's ride cymbal swings. Lean slightly forward into the beat rather than dragging behind it.

Chord tones on strong beats

In 4/4, beats 1 and 3 are the strong beats. The simplest way to make a line sound correct is to put chord tones there: the root on beat 1 almost always, and the third, fifth or seventh on beat 3. Beats 2 and 4 are the weak beats, where passing notes and approach notes live.

For a dominant seventh chord like F7, the chord tones are F, A, C and Eb. Here they are across the lower part of the neck:

Target notes and approach notes

The target note is the note you want to land on at the start of the next bar, usually the root of the next chord. The note on beat 4 is the approach note that leads into it. Think backwards: decide where you are going, then how to get there.

There are four approaches every walking bassist uses:

• Chromatic from below: one fret under the target (F# into G).
• Chromatic from above: one fret over the target (Ab into G).
• Scale step: the note of the key a step above or below (A or F into G in C major).
• Dominant: the fifth of the target chord (D into G).

Here are all four leading into G on the E string:

Chromatic approaches pull hardest because they move by a semitone. Scale steps sound smoother; dominant approaches sound confident.

Common walking patterns

You do not have to invent every bar from scratch. A handful of four-note shapes cover most situations. Each pattern starts on the root and uses beat 4 to approach the next chord.

Mix these freely. If one bar climbs, let the next descend: this keeps you in one area of the neck.

Walking over a 12-bar blues

The blues is the classic place to learn walking. We will use the 12-bar blues in F, a very common key for horns and jazz groups. The chords are F7 (I7), Bb7 (IV7) and C7 (V7):

Here is a complete written line. Every bar puts a chord tone on beats 1 and 3, and almost every beat 4 approaches the next bar by a semitone.

• Bar 1 (F7): F, A, C, then B as a chromatic approach from above into Bb.
• Bar 2 (Bb7): Bb, C, D, then E from below into F.
• Bar 3 (F7): F, G, A, then Gb from above back to F.
• Bar 4 (F7): F, Eb, C, then B from above into Bb.

• Bar 5 (Bb7): Bb, D, F, then A from below into the high Bb.
• Bar 6 (Bb7): Bb, Ab, F, then Gb from above into F.
• Bar 7 (F7): F, A, C, A. No approach here: the line simply falls back to F.
• Bar 8 (F7): F, G, A, then B from below into C.

• Bar 9 (C7): C, Bb, G, then A from below into Bb.
• Bar 10 (Bb7): Bb, F, D, then E from below into F.
• Bar 11 (F7): F, Eb, C, then B from below into C.
• Bar 12 (C7): C, Bb, G, then F# from above into the low F at the top of the form.

Loop the whole form slowly, then change one bar at a time using the patterns above.

Walking over a ii–V–I

The ii–V–I is the most important progression in jazz. In C major it is Dm7, G7, Cmaj7. Each chord usually lasts one bar, or two beats each in faster tunes.

A written line over one bar per chord:

• Dm7: D, F, A (the arpeggio), then Ab from above into G.
• G7: G, F, D, then B from below into C.
• Cmaj7: C, E, G, B, climbing straight up the chord. B leads by a semitone into the high C.
• Cmaj7: C, A, G, then Eb from above back into D for the next repeat.

The G7 bar descends after the Dm7 bar climbs. That balance keeps the line in one position and makes it sound like a melody.

How to practise walking bass

1. Roots only. Play the root of each chord on all four beats through the blues. Learn the form by heart.
2. Root and fifth. Play root, root, fifth, fifth. Now you are moving but staying safe.
3. Arpeggios. Play 1-3-5-3 or 1-3-5-b7 on every chord. Your hand learns the chord shapes.
4. Add approaches. Keep the arpeggios but replace beat 4 with a chromatic approach into the next root.
5. Mix patterns. Choose a different pattern for each bar. Aim to change direction often.

Record yourself and listen back: are all notes the same length, does beat 1 land on a clear chord tone, and does the line lead somewhere?

Common mistakes

• Rushing beat 4. The approach note is the most exciting note of the bar, and players tend to play it early. Keep it exactly on time.
• Running out of neck. If you keep climbing, you will end up too high. Change direction at least every two bars.
• Ignoring chord quality. Over Dm7 the third is F, over D7 it is F#. Know the chord before choosing your third.

Practice

1. Approach drill: pick a target note and play the four approaches into it, ten times each, at 60 BPM.
2. Blues form: play the written F blues line from start to finish at 80 BPM three times without stopping.
3. Your own blues: keep beats 1 and 3 from the written line, but choose new notes for beats 2 and 4.
4. ii–V–I in all keys: move the ii–V–I line to F, Bb and G by shifting the shapes on the neck.
5. Metronome on 2 and 4: set the click to half the tempo and feel it as beats 2 and 4, like a drummer's hi-hat.
