Harmonics (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
