Bass Hub — the fretboard, the scales, the notes

The Bass Hub helps you see the fretboard: where the notes fall on a 4-string bass (E-A-D-G), how the scales take shape, and how to lay down a line that fits the song's chords.

The fretboard, fret by fret

The 4-string bass fretboard (E-A-D-G) is shown in full: every note is marked fret by fret, so you can memorize the positions and stop hunting for the root by ear.

Scales under your fingers

Pick a key and a scale: the hub lights up the matching notes on the fretboard. You can see the patterns repeat from one string to the next and build your bass lines from the right anchor notes.

Tied to the chord book

Like every hub in the Maurisson Music Hub, the bass pairs with the chord book: you read a song's chart, spot the root of each chord, lay down the line. Consistent with the piano popover and the scale tools.
