| === Octave stretch ===
| |
| 39edo's approximations of harmonics 3, 5, 7, and 11 can all be improved by slightly [[octave shrinking|compressing the octave]], using tunings such as [[62edt]] or [[101ed6]]. [[equal tuning|18ed11/8]], a heavily compressed version of 39edo where the harmonics 13 and 17 are brought to tune at the cost of a worse 11, is also a possible choice.

| There are also some nearby [[zeta peak index]] (ZPI) tunings which can be used for this same purpose: 171zpi, 172zpi and 173zpi. The main zeta peak index page details all three tunings.
