Why it sounds like that

Start with A♭ major and sharpen the fifth from E♭ to E. That single change produces the ionian augmented scale, with a whole-and-a-half step between D♭ and E. Compare it with A♭ major to isolate the altered degree.

When to use it

Use it over A♭ augmented or A♭ augmented major 7th. The scale also works over A♭ major progressions when you want a sharp-five colour. It suits jazz and fusion contexts.

Which position to practise

Practise Box 1 first. It keeps the root on string 6, fret 4 and spans frets 0–3, giving easy access to the augmented fifth on string 5.
