//A brief example of using "magic temperament" http://xenharmonic.wikispaces.com/Magic+family
to equate the intervals 36/35 and 25/24 into one "semitone" step, specifically to distinguish between seventh chords using 7:4 and 9:5, i.e. harmonic 4:5:6:7 chords and traditional "dominant" chords tuned with a 6:5 above the 3:2. For analog organ and faded chrysanthemum-Cameron Bobro//

//A brief demonstration of the near-Just musical temperament which flattens the pure major third of 5:4 by a few cents, such that 5 major thirds does not exceed 3:1 (a pure fifth + 1 octave), but meets it precisely. In a purely tuned system, the thirds would exceed 3:1 by what is known as the small diesis, (a ratio 3125/3072, about thirty cents). This temperament, then, brings (almost) pure thirds and pure fifths together. Cameron Bobro//

//The earliest implementation (by happy accident, it seems) of this temperament was, to my knowledge, by Paul von Janko over a century ago. More recently, an online tuning community has elaborated many precise variations, calling the temperament "magic".. This piece is a demonstration of the array of pitches created by using 22 generators (the slightly tempered 5:4) within the octave, an approach which creates a "moment of symmetry", with all pitches separated by the same two intervals. This has many curious repercussions, creating some musical possibilities and restricting others. Cameron Bobro//</pre></div>

This implies that the &lt;a class="wiki_link" href="/magic%20comma"&gt;magic comma&lt;/a&gt; 3125/3072 is tempered out, making it a member of the &lt;a class="wiki_link" href="/Magic%20family"&gt;Magic family&lt;/a&gt;. 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 &lt;a class="wiki_link" href="/Magic%20family#Muggles"&gt;muggles&lt;/a&gt;, but there's basically no reason to use it unless you're using &lt;a class="wiki_link" href="/19edo"&gt;19edo&lt;/a&gt;, in which case it's identical to magic anyway.)&lt;br /&gt;
