MIAGO TROD

Miago Trod is a set of 22 threaded rods up to 42” long, mounted in a frame, tuned chromatically and played by percussion. The main mounting pieces are two heavy steel bars, and each rod passes through its mounting bar with a shorter playable segment above and a longer playable segment below. The segments are long enough that the fundamentals are subsonic, and the tone that you hear is that of various overtones. The range of rod lengths is chosen so that one overtone is strong enough to stand out as the defining pitch, while other overtones contribute to a reasonably coherent blend enhanced by the addition of a well placed weight partway along the rod to deliberately modify the overtone relationships. The lower segments are pitched an octave below the upper segments, and when either is struck, the two parts interact to further enrich the tone.
