An electronic musical instrument which can be designed compact in longitudinal size and is excellent in acoustic characteristics. A musical instrument main body (1) has at least one keyboard device (12), and left and right lateral side panels (13 and 13'). A musical tone signal is generated by a controller (101) through operation of the keyboard device. The musical tone signal generated by the controller is acoustically converted by at least one speaker (31 or 31'). The musical instrument main body is supported by left and right front legs (2 and 2') in the vicinity of the left and right lateral side panels of the musical instrument main body. An upper part of each front leg is secured to the musical instrument main body, and a lower part thereof extends to a floor surface on which the electronic musical instrument is placed. The speaker is held in a speaker box (3 or 3'). The speaker box serves as a supporting member that supports a rear side part of the musical instrument main body. The speaker box has a lower part extending to the floor surface to serve as a rear leg.
