According to astronomers, there are three principal forms of galaxies: spiral, elliptical, and peculiar. Many of the latter galaxies have peculiar shapes because they are undergoing a near miss or perhaps even a merger with another galaxy, as our own galaxy will experience when it meets up with the Andromeda galaxy in approximately four billion years.
The video imagery for this work consists of animations (with additional processing) of telescopic photographs of the galaxies NGC 4038 and 4039. The pitches in this piece are based on a dorian scale, tuned in 5-limit just-intonation, that is friendly to both quartal and tertian harmonies (i.e., harmonies built of fourths or thirds, respectively).
