C Phrygian — Double Bass

The C Phrygian scale runs 7 notes per octave in the modes 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.

Very dark minor with a half-step above the tonic. Spanish, Flamenco, and metal flavor — exotic, tense, and mysterious.

Heard in: Flamenco, metal, dark film scores — Carlos Santana solos, Joe Satriani's "War", Moorish and Andalusian music.

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 C and let the scale turn into lines.
