Why it sounds like that
Start with F♯ major and sharpen the fifth from C♯ to C♯♯. That single change produces the ionian augmented scale, with a whole-and-a-half step between B and C♯♯. Compare it with F♯ major to isolate the altered degree.
When to use it
Use it over F♯ augmented or F♯ augmented major 7th. The scale also works over F♯ 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 2 and spans frets 2–5, giving easy access to the augmented fifth on string 5.
