assistant
A piano is a keyboard instrument that uses wooden hammers to strike a string which produces a sound.  The hammers on a piano are coated with a soft material so they do not damage the string they hit when a keyboard key is pressed.  You have to play this keyboard instrument with one or two hands in sync on a keyboard and then the keys hit in unified succession you get music or a string of sounds that is enjoyable to listen to.
