'''18/11''', is an '''undecimal neutral sixth''', and the [[octave complement]] of [[11/9]], the difference between the 11th and 9th harmonic. As this is the larger of two [[11-limit]] neutral sixths obtained by modifying Pythagorean intervals by [[33/32]], it is dubbed the '''greater Alpharabian neutral sixth''' in [[Alpharabian tuning]].

18/11 is an undecimal neutral sixth, and the octave complement of 11/9, the difference between the 11th and 9th harmonics. As this is the larger of two 11-limit neutral sixths obtained by modifying Pythagorean intervals by 33/32, it is dubbed the Alpharabian tendoneutral sixth in Alpharabian tuning.
