Vibrations in Strings
Fundamental Mode (First Harmonic)
Fundamental Mode – when a string is plucked, it will vibrate in one segment with two nodes at either end.
This is the lowest possible mode of vibration
In a guitar string, for example, it will vibrate between the fret and the tuning key. The bridge transfers the vibration to the “box” (or sound box) through the saddle.
At the fundamental frequency (f0) we have 1 loop and 2 nodes.
Note: # of nodes = # of loops +1
Also: L = ½ λ (L – length of the string, λ – wavelength)
Overtones – when strings vibrate in more than one segment.
Harmonies – frequencies which are multiples of the fundamental.
i.e. 2f0, 3f0 …
The fundamental frequency (f0) is known as the First Harmonic.
