(1.11) Chromatic Scale for Piano
The piano keyboard is one of the classic ways of viewing the Chromatic scale.
Notice how the white keys play the simple notes (called natural notes) and the black keys play the altered notes (which have sharps or flats added). Also, the whole pattern of note names repeats after every seven white notes.
