A stringed instrument, such as a semi-acoustic electric guitar, can employ a resonance system that consists of a body having at least one internal cavity accessed by a soundhole continuously extending from a top cover. The soundhole may have a continuously curvilinear transition from the top cover and a length corresponding with an altered resonance frequency of the instrument body.
