A '''fixed-center flip''' is a chord progression of the form a:b:c <-> 1/c:1/b:1/a, where the b of the first chord is the same as the 1/b of the second chord. | A '''fixed-center flip''' is a chord progression of the form a:b:c <-> 1/c:1/b:1/a, where the b of the first chord is the same as the 1/b of the second chord. | ||
A scale is '''flippery'''{{idiosyncratic}} (term proposed by Praimhin) if every step of the scale is part of either a fixed frame flip or a fixed center flip using only notes in the scale. | A scale is '''flippery'''{{idiosyncratic}} (term proposed by [[Praimhin]]) if every step of the scale is part of either a fixed frame flip or a fixed center flip using only notes in the scale. | ||

* A hypothetical fixed frame flip involving the step 5/3-16/9 would look like 4/3:5/3:20/9 → 4/3:16/9:20/9, but neither the note 4/3 nor 10/9 (octave reduced 20/9) are in the scale. | * A hypothetical fixed frame flip involving the step 5/3-16/9 would look like 4/3:5/3:20/9 → 4/3:16/9:20/9, but neither the note 4/3 nor 10/9 (octave reduced 20/9) are in the scale. | ||
