'''18/11''' is an '''undecimal neutral sixth''', and the [[octave complement]] of [[11/9]], the difference between the 11th and 9th [[harmonic]]s. 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]].
