common-divisor

Updated: May 7, 2025

Unison of musical notes is attained when the respective numbers of pulsations per second admit a low common-divisor. For instance, the note produced by 60 vibrations per second will chord with one produced by 120 each node of the former coinciding with each alternate node of the latter. 60 and 90 will also chord; 60 and 70 will produce discord; 60 and 65, worse discord. And so on.
