How to play B Phrygian b4 on guitar
Find the root first: B is at fret 7 on the low E string and fret 2 on the A string. The blue notes on the diagram are every B on the neck; the gold ones are the rest of the scale's home chord (♭3, 5, ♭7), the safest notes to land on at the end of a phrase.
Learn it one box at a time. Position 1, the E shape, sits at frets 7–11. Once it's under your fingers, move to position 2 (the D shape) and play the notes the two boxes share, then keep going up the neck. After all five, the scale joins up into one pattern across the whole fretboard.
