Lydian dominant · A · Guitar
The A Lydian dominant scale is A B C♯ D♯ E F♯ G — formula 1 2 3 ♯4 5 6 ♭7, step pattern W–W–W–H–W–H–W. Use it over A7♯11: it is the scale for dominant chords that do not resolve down a fifth — tritone substitutes, IV7, and 7♯11 chords. Below, every note is marked on the fretboard in standard tuning; press play to hear it on a synthesized guitar while each note lights up, or tap any fret to sound that note.

Start on the root A on the low E string at fret 5, and play the one-octave position shown: E-string fret 5, E-string fret 7, E-string fret 9, A-string fret 6, A-string fret 7, A-string fret 9, D-string fret 5, D-string fret 7. Every A on the neck is a root, so the same shape works in every position where the notes are marked.
