Text: The Ninth Natural Ninth The chord includes the pitch a major ninth (major second) above the root of chord when the numeral 9 is part of the chord symbol. Lowered Ninth The chord includes the pitch a minor ninth (minor second) above the root of the chord when (9) is part of the chord symbol. The symbol (9) is preferred indicator, but (-9) is also used. This alteration occurs on dominant seventh type chords. Raised Ninth The chord includes the pitch an augmented ninth (augmented second, usually spelled enharmonically as a minor third) above the root of the chord when (9) is part of the chord symbol. The symbol (9) is the preferred indicator, but (+9) is also used. This alteration occurs on dominant seventh type chords. (SEE graphics on 9ths.)
