Abstract
A drum with a vibrating membrane for producing sounds in a range of low to high resonant frequencies including a drum shell with a first open end and a second open end, a drumhead, including a vibrating membrane, covering said first open end, a cover with a threaded opening extending across and secured to said second end, and a resonant member having a first end and a second end, with the first end having a threaded means for detachable coupling with the threaded opening in the cap in airtight relation to enhance and manipulate the low resonant frequencies independent of the high resonant frequencies upon the striking of the membrane.

A drum with a vibrating membrane for producing sounds in a range of low to high resonant frequencies, comprising:
- A drum shell having a first open end and a second open end;
- A drumhead having a sound vibrating membrane covering said first open end;
- A cover having a threaded opening extending across and secured to said second open end;
- A resonant member having a first end and a second end, said first end having a threaded means for detachable coupling with said threaded opening in said cover in airtight relation to enhance and manipulate said low resonant frequencies independent of said high resonant frequencies upon the striking of said membrane.
A percussion instrument comprising a box-like container with four side walls and a first end wall and a second end wall, said first end wall having a vibrating means and said second end wall having a threaded opening, and a resonant member having a first end and a second end, said first end having a threaded means for detachable coupling with said threaded opening in airtight relation to enhance and manipulate said low resonant frequencies independent of said high resonant frequencies upon the striking of said membrane.
