Abstract
When a switch is activated while a help switch for designating a help operation is activated, the explanation of a function assigned to the activated switch during a current operation mode is displayed on a display, without executing the function assigned to the activated switch. In an electronic musical instrument of the type having switches whose functions change with the operation mode, it is possible to readily know the function of each switch without relying upon a voluminous manual, and easily know how to manipulate switches in order to realize a desired function.
