Harmonics only increase the frequency though, right? Not decrease? You can't get an octave lower note from plucking a guitar string in a certain way.

- ithkuil 10y agoHarmonics (overtones) are already there. By definition the fundamental tone is just the lowest frequency. You can isolate harmonics either by amplifying the desired frequency or by muting a longer wave length e.g. by placing a finger on a string in a place that is a node of the higher frequency harmonics but not a node in the lower frequency. Thus by definition you cannot create subharmonics, well unless you cheat :-) http://www.marikimura.com/subharmonics.html http://www.marikimura.com/subharmonics.html
- DINKDINK 10y agoHarmonics are caused by the different modes that any entity vibrates at (physical, electrical, or magnetic). If you strike and object with an impulse a rich array of vibrations will occur (think of a gong, a snare, a garage door) all of those modes will be present if you repeatedly strike or oscillate the object.
