Phrygian is a minor mode with a ♭2, giving it a dark Spanish/flamenco and metal flavour built on that half-step above the root. On guitar, the bb phrygian scale uses the notes B♭, B, D♭, E♭, F, G♭, A♭ — the diagram above shows every one of them across all positions of the neck, with the root (Bb) highlighted so you can anchor each shape.
KnowYourNeck turns this into an interactive neck you can rotate through every position, switch between note names and scale degrees, and drill one box at a time with Focus Mode. It's the fastest way to actually learn the phrygian scale instead of just reading a chart.
