Abstract

A turn-on tuning system comprising threaded tuning rims or drumheads with threaded frames in place of lugs used by conventional drums, and a spherical acoustic chamber to provide both acoustic and visual improvements over prior art instruments. The tuning system secures a drumhead to a drum by either sandwiching the drumhead between a threaded drum shell and a threaded rim or by directly attaching the drumhead to the threaded drum shell via a threaded frame integral with the drumhead. The drum is tuned by rotating the rim or drumhead to increase pressure on the drumhead. The spherical acoustic chamber, which may be attached to or in place of a traditional drum shell, provides enhanced audio quality and may also provide housing for electronic equipment or acoustic elements which may be held within the spherical chamber. The spherical acoustic chamber also provides numerous visual improvements.
