The island tetrad is an [[Dyadic chord#Essentially tempered dyadic chords|essentially tempered dyadic chord]] which under [[octave reduction]] consists of three [[15_13|15/13]] intervals followed by a [[13_10|13/10]], which closes on the octave since the [[island comma]], [[676_675|676/675]], is [[tempering out|tempered out]]; in other words a 15/13-15/13-15/13-13/10 chord. It can also be viewed as an island tempered version of 1-15/13-[[4_3|4/3]]-[[20_13|20/13]]. Contained within it are a [[barbados triad]], the 1-13/10-[[3_2|3/2]] chord, and an [[island triad]], the 1-15/13-4/3 chord, which in another position is the 1-3/2-[[26_15|26/15]] chord.
