How do I finger B♭ Augmented on Piano?
On piano, scales typically use a 1-2-3 / 1-2-3-4 thumb-under pattern for white-key scales. Black-key scales (F♯, G♭, etc.) shift the thumb-under positions onto white keys for ergonomic clearance. Hanon Exercise No. 1 and Czerny Op. 599 No. 1 work through the canonical pattern.
When would I use the Augmented scale?
Alternating minor 3rd and half step. Six notes; symmetric every major 3rd. Modern jazz / fusion colour.
