EDO


    Equal Divisions of the Octave. I agree with Dan Stearns and others this term is better than ET for describing ETs that are divisions of an 'octave' (assumed to be tuned to the ratio 2:1), because the 'octave' is not the only interval that may be evenly divided.

    For example, 19-tET or 19-ET, altho they standardly refer to 2^(19/19), could mean 19 divisions of any pitch range, not neccesarily an octave. For example, the 3:1 'perfect 12th' (that is, 'octave' plus 'fifth') could be divided into 19 equal parts: 3^(19/19).
