The metal bar of the metallophones some said to me are non-harmonic,  
but they couple to resonators. Something similar happens in timpani:  
without the bell, the partials might be sqrt(k), k = 1, 2, 3, ..., or  
something, but one strikes it as to suppress the fundamental, and the  
coupling causes the first few partials to be fairly harmonic.

So a question might be how to make such a resonator coupling in ChucK.  
There is a UGen for a metal bar.
