Scales on bass

Scale lab

Pick a root and a scale. The neck marks the notes, the TAB shows one in-position path through them, and Play walks that path so you hear it before you own it. Squares are roots. BPM follows the practice bar at the bottom.

1. Major — the reference map, and the one that teaches the shift.
2. Minor pentatonic — five notes, the fill vocabulary.
3. Natural minor, then Dorian and Mixolydian in the lab above — one changed note each.
4. Degrees — name what you are playing while you play it.
5. Sequences and rhythm, then use them as fills in Play along.

Root on the E string, fret 3. The octave is the open G string — the same pitch twelve frets up, which is why this shape is worth knowing first: it shows you how far one octave reaches on a bass.

G|---------------0-
D|---------0-2-4---
A|---0-2-3---------
E|-3---------------

Three notes on the E string, three on the A, two on the D. Nothing stretches: the hand covers frets 3 to 5 and the rest is open strings and one reach to fret 4. Descend it too — most players can only play their scales upwards, which is not the same as knowing them.

Root A on the E string, fret 5, and the box sits in frets 5 to 8. Five notes — A C D E G — which is why it fits under almost any minor-flavoured groove.

G|-------------5-7-
D|---------5-7-----
A|-----5-7---------
E|-5-8-------------

The fret-8 note is the flat third, the one that gives the box its colour. Everything above is the same five notes an octave up, so once this shape is in your hand you already know the next one.

Straight ascending is the least musical thing you can do with a scale. Three ways out, in order of difficulty:

• Groups of three — up three notes, back one, repeat. Forces you to think in shapes rather than in a line.
• Skips — every other note. Sounds like a bassline immediately.
• One rhythm, borrowed — play the box on a gallop cell from Gallop or a groove rhythm from Grooves. Same pitches, completely different job.

Then improvise two-bar phrases that end on A, C or E and stop. The stopping is the exercise.

A scale played on autopilot teaches your fingers and nothing else. Name degrees as you go: over A minor, A is 1, C is ♭3, E is 5 — those three are landings. B, D, F and G are passing colour, good in the middle of a phrase and weak at the end of one.

Two drills that make this stick:

• Play only degree 1 for a bar, then only 5, then 1–♭3–5 as an arpeggio inside the box.
• Forbid the root for four bars. Phrases have to land on ♭3 or 5, which is where most of the interesting bass playing lives anyway. More on Lead bass.

Once the one-octave shape is clean, do not reverse at the top — keep going into the next position. The shift is the actual skill: move the whole hand, land with the first finger, and let the last note of the old position ring while you travel. Do not stretch the pinky to avoid moving; that is how bassists hurt their hands.

Position tours across the whole neck are on Shapes & positions, on the click in position drills.

• Only ascending. Descend, skip, and start from the middle of the shape.
• No rhythm. A scale with no pulse is a finger exercise, not music.
• Stretching instead of shifting. Four frets is a hand; five is a shift.
• Collecting shapes. One box you can improvise with beats five you can only run.
• Notes that do not speak. Every pitch in the box should sound, or the shape is hiding a muted note from you.
