|HARMONIC CANON I (As rebuilt 1959)
||1945, at the University of Wisconsin. Rebuilt at the University of Illinois.
||37 inches high at the back, and 28 inches in front. The resonating box is 27 inches broad, 28 inches across the strings, and 3.5 inches deep.
||The base and rack are Plexiglas. The resonating box, including the thin soundboards, is redwood.
||Two sets of 44 strings each are strung on different planes. The first set -- mostly guitar second strings -- is horizontal. The second set -- all tenor guitar first strings, dips from a high nut at the right to a lower set of tuning pegs at the left. The two sets intersect about seven inches from the right. Consequently, there is a choice of either set, or both together. The first set has guitar fourth and fifth strings on the lowest sixteen, and a Pyrex bar beneath them provides gliding tones.
