This handout provides an overview of how the two different forms of scale-degrees six and seven are used in common-practice music. It was initially created as a reference for upper-level undergraduate students studying eighteenth-century counterpoint. It contains five sections: (1) The Minor Scale (pp. 1–2); (2) Diatonic Triads and Seventh Chords (pp. 3–4); (3) Voice Leading (pp. 4–5); (4) Harmony (pp. 6–10); (5) Melodic Figuration (pp. 11–14). The appendix to the handout provides examples of harmonic progressions that feature the raised form of scale-degree six or the lowered form of scale-degree seven. The examples are organized according to the four types of harmonic progression discussed on pp. 6–10 of the handout.
