reduced harmonic
[sound info]
The Pythagorean major third, 81/64, may be reached by stacking four perfect fifths (3/2), and reducing by two octaves. In contrast to the more typical 5/4- with which it is conflated in meantone- this interval is a bit more dissonant when not bridged by a stack of 3/2 within in a chord, and thus, some would argue that it is either imperfect consonance or an imperfect dissonance depending on the setting.
