PURPOSE:To obtain visual effect which can not be obtained with a display of a range or interval based upon a simple array of light emitting elements by using a small number of light emission display means made to correspond to key codes for the electronic musical instrument. CONSTITUTION:Display signals are generated, range by range, according to given key codes. A light emission means having light emission display parts 14, 16, and 18 corresponding to the ranges is provided to make light emission displays, range by range. The display parts 14, 16, and 18 for the respective ranges have light emission patterns in different shapes corresponding to intervals. For example, a display pattern which is different in length or thickness like a string of a musical instrument and a display corresponding to the range are combined to obtain unique visual effect. |
