We have a waveshape demonstration exhibit where visitors can explore the shapes of sound.  The exhibit consists of a 503 Oscilloscope, a Rodgers Organ synthesizer, a tube Theremin, a microphone, three organ pipes, and a guitar.

With the Rodgers Organ synthesizer you can visualize the sounds of different acoustic and electric instruments and what makes them bright or soft sounding.  You can use the keyboard to visualize resulting waveshapes with different frequency content.

The microphone can be used to make your own sounds and explore the waveshapes, or you can listen to the sounds different objects such as the organ pipes.

The guitar can be used to demonstrate wavelength vs. frequency and different waveshapes.

The theremin is a great hands-free exhibit for looking at frequency and amplitude. This is often the highlight of a tour. We've upgraded to the new Moog Theremini. It has a number of different sounds, effects, and functions and is even more fun to play.

Come in and give them a try.
