Want to know the key to staying in touch? Good communication. And there is nothing that strikes a chord than a personal note. So why not write someone and let them know what's new? Modern pianos commonly have 88 keys -- 52 white keys and 36 black keys, Wikipedia notes. The black keys were traditionally made of ebony, and the white keys were covered with strips of ivory. However, since ivory is protected by treaty, makers use plastics almost exclusively. In simplest terms, when a key is struck, it starts a chain reaction whereby it riases a hammer that hits a wire string and sets it vibrating to make the sound note.
