The '''tritone''' is the name of a musical interval that is made up of three [[Tone|whole tones]]. In [[12edo]] the tritone is exactly 600 | The '''tritone''' is the name of a musical interval that is made up of three [[Tone|whole tones]]. In [[12edo]], the tritone is exactly 600{{cent}}, or sqrt(2). As such, the term is also used generally to refer to any pitch in the neighborhood of 600{{cent}}, or roughly halfway between [[4/3]] and [[3/2]]. | ||
In tunings other than 12edo, and particularly in [[just intonation]], there are a number of different tritones which have subtly different flavors, such as [[7/5]] and [[10/7]]. The temperament eliminating [[50/49]] is of particular interest in that it equates these two tritones, and provides a JI basis for the 12edo concept of the "tritone substitution". | In tunings other than 12edo, and particularly in [[just intonation]], there are a number of different tritones which have subtly different flavors, such as [[7/5]] and [[10/7]].
