Gold­en Ra­tio

The “pitch” of these notes, or their fre­quen­cies of vibra­t­ion, are in a ra­tio of about 1.618, the same “the gold­en ra­tio fa­mous from art and ar­chi­tec­ture,” he con­tin­ued. If two num­bers are re­lat­ed by the gold­en ra­tio, their sum is al­so re­lat­ed to the larg­er of them by the gold­en ra­tio. In oth­er words, if A di­vid­ed by B is that spe­cial num­ber, then A+B di­vid­ed by A is the same num­ber.
