A musical keyboard is a versatile instrument that consists of a set of keys or buttons arranged in a specific order. When the keys are pressed, they produce different pitches and tones, allowing musicians to play melodies, chords, and harmonies. The keyboard is often associated with the piano, but it can also be found in various electronic synthesizers and other musical instruments. It provides a wide range of expressive possibilities and is widely used in many genres of music, from classical to jazz, pop, and rock.
