Common meantone tunings can be classified into eigenmonzo tunings, | Common meantone tunings can be classified into eigenmonzo tunings, edo tunings, prime-optimized tunings and others. In [[eigenmonzo]] tunings such as the [[quarter-comma meantone]], a certain interval is tuned pure and certain others are equally off. Edo tunings like [[31edo]] have rational size relationship between steps, and happen to send an additional comma to unison. Prime-optimized tunings are optimized for all intervals. For a more complete list, see the table below. These different tunings are referred to as "temperaments" in traditional terms. | ||
