The piano may well be the most familiar and well known musical instrument of all time. The versatility of being able to play so many different styles of music on the piano, as a soloist or in an ensemble, accompanying other instruments, or for use in composing and in rehearsals for such things as dance and stage, lends itself to its popularity.
They keyboard has 88 keys (52 black and 36 white) that determine which tone we hear when pressed by fingers from both hands. Pressing a key on the piano causes a padded hammer to strike the strings inside. The hammer rebounds while the strings continue to vibrate. When the key is released, a damper stops the vibration, ending the sound. Although an acoustic piano has strings, it is usually classified as a percussion instrument because the strings are struck rather than plucked.
Pianos come in all shapes and sizes and decorate its location not only with sound, but with design.
