A piano keyboard is a musical instrument consisting of a series of keys that produce sound when pressed. It typically has 88 keys, which include both white and black keys. The white keys represent the natural notes, while the black keys represent the sharps and flats. Each key corresponds to a specific pitch, allowing musicians to play melodies and harmonies. The layout of the keyboard is designed to be intuitive, with the pattern of black and white keys repeating every octave. This makes it easier for players to navigate and find notes. The piano is commonly used in various music genres, including classical, jazz, and pop.
