'''11/6''' is the '''undecimal neutral seventh''' of about 1049.4 [[cent]]s. It can be treated as a consonance in [[11-limit]] harmony, forming a part of such chords as 6:7:9:11 (1-[[7/6]]-[[3/2]]-11/6) and the [[neutral tetrad]] 18:22:27:33 (1-[[11/9]]-[[3/2]]-11/6). | '''11/6''' is the '''undecimal neutral seventh''' of about 1049.4 [[cent]]s.
