[0004] U.S. Patent No. 6,407,324 discloses a note indicator for a piano. Its principle is to assign one (two in the middle area, for distinguishing left and right hands) LED (light-emitting diode) for each key of the piano. When there is a key, the LED above the key lights up, prompting the user to play the key. The disadvantage is that each key has only one LED at the same time to indicate the note, and the amount of information is too small for the user to obtain the current key. The length information of the note and the information of the note to be played cannot be arranged as a whole
