No one has taken me up on the offer yet, so I haven't actually done it.> Greetings, As I understand it, there exist particular relationships between frequencies of impelling force and a resonant period. If the frequency of an applied force is higher than the resonant period of an object, the two will be out of phase with one another. If the frequency is lower than the resonant period, they will be in phase, though not necessarily in sync. I treated the altered string of the unison as the impelling force in regards to the two that were tuned as mathematically close to one another as possible. I was hoping to create a slight cancelling effect within the unison, the aim of which was to produce a rather shrill, percussive sound. I think it worked, but perhaps will try the opposite, as Wally suggested, next time. Why not, "Out of tune" is out of tune, no? Which is why I tuned the tonk slightly sharp. Regards, Ed Foote
