Description:

Music Science Project This drawing shows on top a drawing of very thin oval on its side with circles at each end. The oval represents the fundamental or first harmonic and the circles represent nodes. Beneath that are two thin ovals hooked together with a circle in the middle and one on each end. Each oval is half the size of the one on top. This represents the second harmonic. Beneath the third harmonic are three thin ovals on their sides hooked together with two circles and circles on each end. This represents the third harmonic.
