音调测定器

He found that the interval of an octave is rooted in the ratio 2:1,that of the fifth in 32,that of the fourth in 4:3.and that of the whole tone in9:8.the phthagoreans applied these ratios to lengths of a string on an instrument called a canon,or monochord(a board with two bridges between which a string is stretched and a third bridge that divide the string in two parts);and thereby were able to determine mathematically the intonation of an entire musical system.

毕达哥拉斯将这些弦长比例应用于一种叫做卡农的乐器上，卡农也可以称之为单弦琴或者单弦音响测定器（是一个由两个码构成的木板，码子之间有一条被拉伸的琴弦，第三个码子位于琴弦两端的码子之间），因此能够用数学的方法测定整个音乐系统的音调。
