An electronic musical instrument for producing musical notes comprises an onset signal sensor for sensing the initiation of a note played on the musical instrument. An electronic fingerboard determines the pitch of the note sensed by the sensor. The electronic fingerboard comprises a silicon rubber membrane, a first layer of film, a second layer of film and a spacer member between the first and second layers of film. The first and second layers are movable relative to each other between a first inactive position in which the first and second layers are separate from each other along their respective lengths and a second active position in which the first and second layers are in contact with each other at a user selected point along their respective lengths. The pitch is determined by the resistance between the first and second layers at the user selected point. |
