Long description

This figure shows the keys of the keyboard (from one C to another an octave above it). All the keys are identified. The white keys are labelled in ascending order as C, D, E, F, G, A, B and C. Each of the black keys is labelled with two names: in ascending order, the first is C sharp and D flat, the second is D sharp and E flat, the third is F sharp and G flat, the fourth is G sharp and A flat, and the fifth is A sharp and B flat.
