The keys in this photograph make up just over an octave of musical tones on a piano.
The black keys are the “sharp” or “flat” sound of the keys next to which they are located. Twelve tones make up one complete octave – which then repeats in several locations (seven plus) on a full-size piano keyboard, which contains 88 keys in total.
The pair of black keys separate the C, D and E tones, while the trio of black keys divide the F G, A and B notes (tones).
The subject piano, in this image, is a Baldwin Spinet Piano built in the 1980’s.
