What are the 61 key piano notes and how are they arranged on a standard piano keyboard?

The 61 key piano notes consist of 36 white keys and 25 black keys. They are arranged in a repeating pattern of groups of 12 notes, with the white keys representing the natural notes (A, B, C, D, E, F, G) and the black keys representing the sharps and flats. The keys are organized in a specific sequence of alternating groups of two and three black keys, which helps pianists navigate the keyboard and play different scales and chords.
