Abstract
In an electronic musical instrument copying a so-called stringed instrument and capable of detecting a depression state of a fingerboard on the basis of an ON/OFF state of a plurality of contacts formed in the fingerboard and determining the pitch of a musical tone to be generated, the plurality of contacts are arranged in a single pitch unit of a pitch designation area corresponding to each string so as to detect a depression position in the pitch unit more precisely, thereby reflecting the detected depression position on an attribute of a musical tone.
