B-flat major scale

How to play the B-flat major scale

Right hand: start on B♭ with finger 4, then tuck your thumb under to play C, then tuck your thumb under to play F.

Left hand: start on B♭ with finger 3, then cross finger 4 over your thumb to play E♭, then cross finger 3 over your thumb to play B♭.

Coming down, use the same fingers in reverse order. Start with each hand alone at a slow tempo, and play hands together only once both feel even.
