Structure
Gb ionian #5 scale notes:
How the ionian #5 scale is built:
The ionian #5 scale is built from the degrees 1 2 3 4 #5 6 7, which gives the step pattern W-W-H-W+H-H-W-H (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 4, 5, 8, 9, 11. That makes it a 7-note scale.
It is mode 3 of the Harmonic Minor Scale, so both scales share the same notes from a different starting point.
It is also known as Ionian Augmented.
