Abstract
An electric guitar having a vibrato function includes first and second operation elements and an operating unit. The first operation element can designate a pitch width to be changed by setting a first pitch width as a unit. The second operation element can designate a pitch width to be changed by setting a pitch width smaller than the first pitch width as a unit. The operating unit performs an operation of the pitch width to be changed, which has been designated by the first operation element, and of the pitch width to be changed, which has been designated by the second operation element. The operating unit forms the control information representing a width of pitch change of a vibrato to be imparted on the basis of the operation result, thereby imparting the vibrato effect on a musical tone to be produced in accordance with the control information.
