In [[common practice period|common practice]] [[tonality]], it usually had subdominant [[Function (music)|function]] as minor eleventh chord on the second degree ([[supertonic]]) of the [[major scale]].<br /> <br /> The [[quarter tone]] scale offers an alternative eleventh of 1650 cents, which is very close to the just interval 11:4, the undecimal eleventh (1651.3 cents).<br /> <br /> ==See also==<br /> *[[Eleventh chord]]<br /> *[[Extended chord]]<br /> <br /> ==References==<br /> {{reflist}}<br /> <br /> {{Intervals}}<br /> {{Chord factors}}<br /> <br /> [[Category:Chord factors]]<br /> [[Category:Fourths (music)]]<br /> [[Category:Compound intervals]]<br /> <br /> {{music-theory-stub}}</div>
