Technical Notes for Newbeams: Difference between revisions

The scale here is a [[MODMOS_Scales|MODMOS]] of Sensi[8] in 46edo. Ordinary ol' Sensi[8] has scale pattern ssLssLsL, with L = 7\46edo ~ 182.6¢, and s = 5\46edo ~ 130.4¢. The difference between L and s is the "chroma", "c", and here it's 2\46edo ~ 52.2¢. Sensi[8]'s "s" is the same as Sensi[11]'s "L", and its "c" is the same as Sensi[11]'s "s". This is to be expected (see Tumbledown Stew above). Anyway, if you add c to L you get "A", an augmented step, and if you subtract c from s you get "d", a diminished step. The form of the MODMOS used in this hyperimprovisation is sssLsssA. Since A is 7\46 + 2\46 = 9\46edo ~ 234.8¢, an approximate 8/7, we have a harmonic seventh above the bottom note in this scale. We also have three intervals of a perfect fifth available, instead of just one, as you'd get in the standard Sensi[8] MOS scale. This improvisation wanders around a lot, but mostly moves between three main chords, each with a perfect fifth above the bass note.
