About This Answer

The modern piano has 88 keys, spanning seven octaves plus a minor third, from A0 to C8. According to the Smithsonian Institution, the 88-key piano became standard in the late 19th century through innovations by piano manufacturers like Steinway & Sons. The Metropolitan Museum of Art documents how piano design evolved from earlier keyboard instruments like the harpsichord and clavichord. Piano historians note that the 88-key configuration provides the optimal range for most classical and modern compositions. This standardization has influenced music education, composition, and performance practices worldwide, making the piano one of the most versatile instruments in Western music.
