Octave stretch or compression

What follows is a comparison of stretched- and compressed-octave EDONAME tunings.

ZPINAME
  • Step size: NNN ¢, octave size: NNN ¢

_ing the octave of EDONAME by a little over 3 ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. The tuning ZPINAME does this.

EDONOI
  • Step size: NNN ¢, octave size: NNN ¢

_ing the octave of EDONAME by a little over 3 ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. The tuning EDONOI does this.
