Inverse Modes

Inverse Modes

Just like chords, every mode (with the exception of symmetrical modes) has a negative counterpart with an inverse formula. Since the Suspended Pentatonic is a symmetrical scale, its modes inverse about mirror lines, similar to the sus4 chord and its inversions. Study the diagram below to see how the scale formulas and LCOF diagrams of the modes inverse about the mirror lines. When naming modes, the negative or inverse naming method can be used to divide the different names by two and immediately describe the inverse formula relationship between two modes. Some of the more interesting inverse modes are the Van der Horst Octatonic, Genus Chromaticum, and Symmetrical Decatonic where there are multiple mirror lines, multiple inverse modes, and the original scale repeats in the scale degrees.
