'''[[Ed5|Division of the 5th harmonic]] into 56 equal parts''' (56ed5) is related to [[24edo|24 edo]], but with the 5/1 rather than the 2/1 being just. The octave is about 5.8656 cents compressed and the step size is about 49.7556 cents. This tuning has a meantone fifth as the number of divisions of the 5th harmonic is multiple of 4. This tuning is also a [[hyperpyth]], tempering out 135/133, 171/169, 225/221, and 1521/1445 in the patent val.

== Theory ==
56ed5 is related to 24edo, but with the 5th harmonic rather than the [[2/1|octave]] being just. The octave is compressed by about 5.8{{c}}, a small but significant deviation. This tuning has a [[meantone]] fifth as the number of divisions of the 5th harmonic is multiple of 4. This tuning is also a [[hyperpyth]], tempering out 135/133, 171/169, 225/221, and 1521/1445 in the patent val.
 
=== Harmonics ===
{{Harmonics in equal|56|5|1|intervals=integer|columns=11}}
{{Harmonics in equal|56|5|1|intervals=integer|columns=12|start=12|collapsed=true|title=Approximation of harmonics in 56ed5 (continued)}}
 
=== Subsets and supersets ===
Since 56 factors into primes as {{nowrap| 2<sup>3</sup> × 7 }}, 56ed5 contains subset ed5's {{EDs|equave=5| 2, 4, 7, 8, 14, and 28 }}.
