H4-21: EDGE TONES
Additional Info
- ID Code: H4-21
- Purpose: Illustrate edge tones and the factors that effect their sound.
-
Description:
Compressed air is blown out a slit onto the point of a wedge-shaped barrier. The wedge can be positioned with respect to the slit and the air flow can be regulated to produce controllable edge tones.
This demonstration can be finicky, and is sensitive to both careful positioning and to environmental conditions. Try it out before hand.
