The '''Pythagorean major third''', '''81/64''', may be reached by stacking four perfect fifths ([[3/2]]), and reducing by two [[octave]]s. 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 | The '''Pythagorean major third''', '''81/64''', may be reached by stacking four perfect fifths ([[3/2]]), and reducing by two [[octave]]s. 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, with a [[harmonic entropy]] level somewhere between that of [[9/8]] and [[8/7]]. Thus, some would argue that it is functionally an imperfect dissonance. | ||
