Abstract
Novel plug devices having tactile and aesthetic properties are disclosed that effectively close the opening within a flute's open-hole key cup, simplify the fingering necessary to play the instrument and improve the instrument's tone, pitch and timbre. When installed near the key cup's upper surface, the key cup has the feel and appearance of a standard key cup. When installed deeper within the key cup, the key cup has the feel of an open-hole key cup.
