Scales to Play Over G#m11
Every chord is a subset of several scales: any scale that contains all of a chord's tones fits over it. Pick a chord to see the matching scales from its own root, the major keys the chord belongs to, and full fretboard diagrams for every scale on guitar.
A G#m11 chord contains the notes G# – A# – B – C# – D# – F#. Any scale that includes every one of those 6 tones fits over it — from the root G#, that means G# Natural Minor, G# Dorian and G# Dorian Bebop. Start with the first scale listed: it is the most common choice, and the others color the same chord tones differently.
G#m11 is also diatonic to 2 major keys: B major (relative minor G#m), F# major (relative minor D#m). In a song from one of those keys you can also solo with the key's own major scale or its relative minor pentatonic across the whole progression, not just this chord.
