90ed10: Difference between revisions

90ed10 is closely related to [[27edo]], but with the 6th harmonic rather than the [[2/1|octave]] being just, which [[stretched and compressed tuning|compresses the octave]] by about 4.11{{c}}. The local [[The Riemann zeta function and tuning #Optimal octave stretch|zeta peak]] around 27 is located at 27.086614, which has a step size of 44.3023{{c}}, making 90ed10 very close to optimal for 27edo.
