Part II Resonating chamber shapes, their Q factor, their resultant musical character Resonating Chambers come in many shapes and sizes and largely determine the power, focus, and sustain of whatever the associated tone bar is coupled with it. The most basic box resonators are found on elementary education musical instruments such as Carl Orff tuned percussion instruments: demonstration of various tone bars resonating over box, rectangular, square and round tube resonators; demonstration of high and low Q systems responding to the same tone bar; demonstration of well-tuned, miss-tuned, and deliberately de-tuned partials on various tone bars; and questions from (and challenges to!) the audience.
