'''Magic''' is a linear temperament in which the ~380 cent generator represents 5/4, and five of those make a 3/1. This implies that the [[ | '''Magic''' is a linear temperament in which the ~380 cent generator represents [[5/4]], and five of those make a 3/1. This implies that the [[magic comma]] 3125/3072 is tempered out, making it a member of the [[magic family]]. This article also assumes the default mapping for the prime 7, which tempers out [[225/224]] and makes two generators equivalent to [[14/9]]. [[7/4]] can be reached by 12 generators in this mapping. (There is an alternative mapping for 7 known as [[Magic family #Muggles|muggles]], but there's basically no reason to use it unless you're using [[19edo]], in which case it's identical to magic anyway.) | ||

Magic has certain properties that commend it as a step up in complexity from traditional harmony: | Magic has certain properties that commend it as a step up in complexity from traditional harmony: | ||
* Every non-trivial 7-limit interval is better tuned than in [[12edo]]. | |||
* It is the simplest mapping with the above property. | |||
* It is only slightly more complex than meantone (both work well with a 19 note gamut). | |||
* 5-limit intervals are simpler than other 7-limit intervals. | |||
It fails to be a panacea because: | It fails to be a panacea because: | ||
* It has no proper MOS scales of between 3 and 16 notes. | |||
* It is more complex than meantone | |||
* The 3/2 approximation is 5 times as complex as the 5/4 approximation (the generator) so modulation by fifths is more constrained than you may be used to. | |||
Because the generator is so close to 1\3 of an octave, and the interval left over (which represents both 128/125 and 25/24) is accordingly so small, all small magic MOSes consist of three large intervals alternating with three groups of this small interval. Specifically, there are the following MOSes, where s always represents the characteristic small interval of 128/125~25/24. | Because the generator is so close to 1\3 of an octave, and the interval left over (which represents both 128/125 and 25/24) is accordingly so small, all small magic MOSes consist of three large intervals alternating with three groups of this small interval.
