In music theory, an eleventh is a compound interval consisting of an octave plus a fourth. A perfect eleventh spans 17 and the augmented eleventh 18 semitones.
Since there are only seven degrees in a diatonic scale, the eleventh degree is the same as the subdominant (IV).[1] The eleventh is considered highly dissonant with the major third.
An eleventh chord is the stacking of five thirds in the span of an eleventh. In common practice tonality, the eleventh chord usually had subdominant function, occurring on the second degree (supertonic) of the major scale.
