Sevish Music

Sevish - The Entity Unmasked (just intonation) (2020x2)

:

An oldschool Sevish track using a tetrachordal scale where each successive interval is a superparticular ratio. A tetrachord is a scale segment containing 4 notes and spanning a perfect fourth. A tetrachordal scale can be formed from two tetrachords. The two tetrachords are separated by an interval of 9/8 (a major second). In this case, I have used the intervals [10/9, 11/10, 12/11] for both tetrachords. Do you notice a pattern with each of the used intervals: 9/8, 10/9, 11/10, 12/11?
