-'''8/3''' is the ratio between the 3rd and 8th harmonics; one octave above [[4/3]].  In non-microtonal music, it is often referred to as the '''perfect eleventh'''.

+== Chord construction ==
+Notably, 8/3 can be used as a framework for chords, but the usage of 8/3 as a framework for chords is intimately connected with the use of [[perfect fifth]]s in the same capacity- at least in [[Octave #Octave equivalence|octave-equivalent]] systems- due to the same pitch classes being involved in both 4:5:6 and 3:5:8 where 5 is kept as the same note, thus rendering the two chords as different voicings of the same underlying harmonic unit.
