This is insane but does let you see what primes are mapped to what
Note -> pitch; prime harmonics -> odd harmonics; note on equivalency to 1afdo and 1ifdo; linking and style

'''1 equal division of the octave''' ('''1edo''') is the [[tuning system]] that contains a single note and the [[octave]]s above and below that note.

One note repeated in octaves is an example of a [[trivial temperament]], it is even a system that demonstrates trivial examples of [[telicity]]. That said, it is actually useful in some cases from a musical standpoint, particularly as a subset of larger EDOs. However, in terms of JI representation, it is simply the [[2-limit]] with all other primes tempered to either the unison or octave.

The first piece of ''Musica ricercata'' by György Ligeti simulates 1edo by playing only one pitch class (A) throughout different octaves on the piano, though the piano is not itself tuned to 1edo. The last chord of the piece uses another pitch class (D), breaking the pattern.

=== Prime harmonics ===
1edo is equivalent to [[AFDO|1afdo]] and [[IFDO|1ifdo]].
