Later, the theory of 12-tone equal temperament was presented by Vincenzio Galilei (c. 1520-91), who took semitones to be 17:18, and Mersenne, who used geometric calculation methods. On the other hand, 53-part equal temperament, as well as 19-, 31-, and 41-part equal temperament were also devised as purely theoretical values. …
