Tritonic scale

Tritonic scales are not common in modern art music[citation needed], and are generally associated with indigenous and prehistoric music.

[2] Early Indian Rig Vedic hymns were tri-tonic, sung in three pitches with no octave: Udatta, Anudatta, and Swarita.

In a 1969 study, Mervyn McLean noted that tritonic scales were the most common among the Maori tribes he surveyed, comprising 47% of the scales used.

[3] The pre-Hispanic herranza ritual music of the Andes is generally tritonic, based on a major triad, and played on the waqra phuku trumpet, violin, and singer with a tinya drum.

The tritonic scale is largely limited to this ritual and to some southern Peruvian Carnival music.
