Scale of the Day: A Mixolydian no 4 mapped to the Square-root-of-2
The A Mixolydian mapped to the Square-root-of-2 Scale. The intervallic "hole" left behind by the subtracted fourth is a mere 150-cents in Square-root-of-2 space. Another artifact of the subtractive process is that the 6-notes per "tritone" will numerically match the equal tempered chromatic scale - making it particularly important to treat each 600-cent tritone as harmonically equivalent to establish the harmonic fabric of this scale.
