Document Summary
The piano has a total of 88 keys, with a recurring pattern of 12 white and black keys. A half-step, or semitone, is the distance between two adjacent keys. Adjacent keys are any two keys directly next to each other, such as c to c# (white to black), c# to d (black to white), or e to f (white to white). A whole-step, or whole tone, is equal to two half-steps. Examples of whole-steps are: c to d (white to white), c# to d# (black to black), e to f# (white to black), and bb to c (black to white). The repeating pattern of notes on the keyboard represents an octave. An octave is the span of eight letter-name notes. The first note of a seven-note scale and the eighth note have an arithmetic relationship of 2:1 in terms of pitch frequency.
