These are lovely instruments (though the big ones are heavy!). I really recommend experimenting with a few once. All rooms and instruments have modes, but on these you can actually see where to strike (or brush, or scrape, or throw rice....) to excited certain modes (the middle of the extruded rims, sometimes indicated with a line). Great fun, and quite inspirational for some modal synthesis. Kas.

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. Hans
