A Rock 'n' Roll — Double Bass

Where A Rock 'n' Roll lives on the EADG fingerboard — roots anchored, audio ready.

The A Rock 'n' Roll scale runs 6 notes per octave in the blues family. Below it sits on the Double Bass'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.

The Double Bass has no frets to trust: the map marks positions on the fingerboard, and the audio is there to keep your intonation honest — match each note by ear, pizzicato first, then with the bow.

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