Abstract
Electronic keyboard instrument is provided with a leg section supporting thereon a keyboard in such a manner that the keyboard is located at a height falling within a range from 350 mm to 500 mm. Namely, the leg section supports thereon the keyboard at a suitable height that is substantially equal to an average height of ordinary low tables designed on the assumption that they are generally used when users are in a comfortable position. Namely, the “height falling within a range from 350 mm to 500 mm” is derived from survey results of heights of low tables. Thus, when the user sits in front of the keyboard instrument, the user can take a comfortable position as when sitting in front of a low table, and, even in such a comfortable position, the keyboard is located at a right height for playing. With such arrangements, the user is allowed, at any desired time, to readily enjoy playing the instrument in a natural playing posture.
