In ancient Greece, Pythagoras, Euclid,
and Ptolemy used an instrument called the kanon to analyze
and play many different kinds of intervals and scales. In Greek,
the word kanon means (1) a straight rule or rod, as in measuring
instrument; and (2) a general rule or principle, as in code of law.
On the Harmonic/Melodic Canon,
all 48 strings are one meter long and are tuned to the same frequency,
thereby giving an aural and mathematical constant. Moveable bridges
then divide the strings into many different and exact frequency
ratios. Since the tuning possibilities on a canon seem endless,
Cris Forster refers to it as a “limited form of infinity.”
