C# Phrygian — Bass (5-String)

The C# Phrygian scale runs 7 notes per octave in the modes family. Below it sits on the Bass (5-String)'s BEADG 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.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the BEADG neck. With the low B in the tuning, the same fingering covers more range before your hand ever shifts.

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.
