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 also be described as a compound fourth, spanning an octave plus a fourth.[1]

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 major third.

A perfect eleventh is an eleventh which spans exactly 17 semitones.
