The Ninth (or Second as guitarists would have it) is the closest thing in music to a chordal MSG. Added to a triad near or at the top of the inversion it possesses the the unique ability to make a major more major and a minor minorior. It is no longer permitted to use the Ninth in the root position for any effect other than irony. This requires form 267-9 to be submitted in triplicicicate.
