How to play Ab Ultraphrygian on guitar
Find the root first: Ab is at fret 4 on the low E string and fret 11 on the A string. The blue notes on the diagram are every Ab 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 4–8. 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.
Ab Ultraphrygian is also written G# Ultraphrygian: G# A B C D# E F. The frets are the same; under that name every note keeps its own letter, with no double sharps or flats.
