All of these scales | All of these scales are tempered by definition. Sometimes multiple scales may generate the same tone, which is why when one combines an x-tone, y-tone and z-tone scale, the total number of tones/octave may still be less than (x+y+z). | ||
This list is not exhaustive. There are many other possible wijzerplaat scales. | |||
