Why it sounds like that

B♭ lydian augmented raises the fourth and fifth of B♭ major, creating a tritone against the root and a leading tone to the tonic. Compare it with B♭ ionian augmented, which keeps the natural fourth but shares the raised fifth.

When to use it

Use B♭ lydian augmented over B♭ augmented or B♭ augmented major 7th. It fits jazz and fusion lines in keys with two flats.

Which position to practise

Practise Box 1 first. Its roots on strings 6, 3, and 1 keep the hand centred from frets 2 to 6.
