'''Intonalism''' is an approach to musical structure in which harmonic areas move according to a complete universe based on [[just intonation]]. Each tonal area is tuned to all other tonal areas by means of pure intervals. | '''Intonalism''' is an approach to musical structure in which harmonic areas {{clarify|define what a harmonic area is, give an example}} move according to a complete universe based on [[just intonation]].

== History == | |||
Intonalism was developed by [[William Copper]] over the period from 2009 - 2016; during this development then-active members of the various Facebook xen harmony pages contributed ideas and suggestions. In Copper's usage, all tonal areas relate to each other using [[5-limit]] just intonation but there is no reason that more extended tonal relations could not be based on higher limit pure intervals. | Intonalism was developed by [[William Copper]] over the period from 2009 - 2016; during this development then-active members of the various Facebook xen harmony pages contributed ideas and suggestions.

In 2020 music educator Adam Neely picked up the term and used it in his [[7th Level of Jazz Harmony|Seven Levels of Jazz Harmony]], with a somewhat different and rather ambiguous intent, where he seemed to describe the use of a tempered scale (often [[12edo]]) for the lead melody of a piece. The current melody note at any given point in time is then treated as a reference pitch, and the current backing chord uses pure just intonation, tuned relative to the current reference pitch. In a sense this is an inverse form of [[adaptive just intonation]] where the bass line adjusts to a tempered scale and the melody and harmony notes tune to it. | In 2020 music educator Adam Neely picked up the term and used it in his [[7th Level of Jazz Harmony|Seven Levels of Jazz Harmony]], with a somewhat different and rather ambiguous intent, where he seemed to describe the use of a tempered scale (often [[12edo]]) for the lead melody of a piece.

This example of the score and notations illustrates several things. The key signature includes a reference notation to indicate where the tonal center is tuned; individual notes are adjusted up or down by syntonic comma as needed; and the final bar illustrated shows one of the many tonal areas found through intonalism but impossible in equal temperament, even beginning from the same reference pitch, in this case A=440. | |||
