Perfect eleventh on C.  Play

In music or music theory an eleventh  play is the note eleven scale degrees from the root of a chord and also the interval between the root and the eleventh. The interval can be also described as a compound fourth, spanning an octave plus a fourth.

Augmented eleventh on C.  Play

Since there are only seven degrees in a diatonic scale the eleventh degree is the same as the subdominant.

The eleventh is considered highly dissonant with the third.

A perfect eleventh is an eleventh which spans exactly 17 semitones. It can be also described as a compound perfect fourth, spanning an octave plus a perfect fourth.
