A link would be nice?

Wolf tones, sound interesting any links perhaps?

Can an inharmonic be phase locked to a harmonic or the fundamental?
Aren't that quite difficult if one wants the inharmonic 
to be continuous without the effect of phase locking has ?

Hmm, a VCO sometimes has the ability to phase lock by stretching the
frequency by the nearby weaker vco until it pops into that stronger frequency, it bends in kind of rubber band effect.

A badly designed filter can also have this effect, the Fc snaps
onto to the fundamental of a wave passing trough the filter
if one modulates Fc perhaps that could count as harmonic stretching
or overtone excitation?.
