'''2ado''', if the attempt is made to use it as an actual scale, would divide the [[octave]] into two arithmetically equal parts. The only intervals in it are [[1/1]] and the just perfect fifth [[3/2]], since 3/2 is arithmetically halfway between 1/1 and 2/1.

{{Harmonics intro|2}} It is equivalent to Subharmonics 2–4, and to the [[1L 1s|monowood]] [[mos scale]] tuned to the just perfect fifth or just perfect fourth. The only non-trivial intervals are the just perfect fifth [[3/2]], since 3/2 is arithmetically halfway between 1/1 and 2/1, and its [[octave complement]] [[4/3]].
2edf's step size is close to the generator of the [[hemififths]] temperament, which tempers out 2401/2400 and 5120/5103 in the 7-limit.
