| '''2ifdo''' ([[IFDO|inverse-arithmetic division of the octave]]), or '''2-UDO''' ([[utonal division]] of the octave), if the attempt is made to use it as an actual scale, would divide the [[octave]] into two inverse-arithmetically equal parts. The only non-trivial interval is the just perfect fourth [[4/3]], since 4/3 is inverse-arithmetically halfway between 1/1 and 2/1.
