G Rock 'n' Roll — Bass (4-String)

The G Rock 'n' Roll scale runs 6 notes per octave in the blues family. Below it sits on the Bass (4-String)'s EADG strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

Major pentatonic with a b3 rubbed against the natural 3 — bright and bouncy with a bluesy smirk. Playful, swinging, and built for boogie riffs.

Heard in: Fifties rock, rockabilly, boogie-woogie, Chuck Berry-style riffs, and jump blues.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the EADG neck.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in G and let the scale turn into lines.
