How where the black and white keys arranged?

The arrangement of black and white keys on a piano follows a repeating pattern of seven white keys and five black keys. The white keys represent the natural notes (A, B, C, D, E, F, G), while the black keys represent the sharps and flats, positioned in groups of two and three. This pattern continues across the keyboard, allowing musicians to easily identify and play notes. The design facilitates both visual and tactile navigation, enhancing musical performance and composition.
