Polymusic makes extensive use of "Polyharmony" which is an experimental usage of two (or more) simultaneous harmonies acting as one. Polyharmony is made up of bitonal hexads or two triads played as one bitonal chord. Each hexad contains two separate fundamentals or half-tonics making up one gigantic bitonal Tonic. An example such as C/D. Polyharmony makes use of what I call "Complex Polychords" which are polychords(slash chords) that can have multiple chords within the chord. In other words, a chord progression can be played over a slower different chord progression. D, E OVER C is an example of a complex polychord. This means that a C chord is played over a progression of D to E. How these chords will officially be notated and what exactly is involved is completely open as of this point as the project is very new and nothing yet has been decided. Polyharmony could involve complexed movement between two or more simultaneous chord changes. Due to this, one problem we're currently facing is avoiding the conflicting harmonies to become muddy.
In addition to polyharmony, polymusic also is polyrhythmic or polymetric meaning that it has the simultaneous uses of multiple rhythms or time signatures being played against each other. Although this portion is simpler than polyharmony, conflicting rhythms can also become muddy or just bad sounding if care isn't taken to experiment and develop the idea. Most likely, the use of traditional time signatures and measures in polymusic will be counterproductive and quickly get very complicated on scores and notation. Therefore, polymusic will also require the development of a new system or alteration of rhythmic notation in order to become more practical.
As of now, the project is extremely new and therefore doesn't have any ground set theories or information yet. Only ideas that have not been tested. Please leave a comment if you're interested in joining the project.
