8/3, the perfect eleventh, is the ratio between the 3rd and 8th harmonics; one octave above 4/3. See also ed8/3.
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 fifths in the same capacity- at least in 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.
