10:13:15, also known as the barbados triad, is a triad in 13-limit just intonation. It is formed by stacking a 13/10 ultramajor third and a 15/13 inframinor third. In terms of harmonics, it is only slightly more complex than 10:12:15, the classical minor triad. It can thus be used as a basis for harmony, for example in barbados temperament.
