NEED A THEORY, HARMONY, OR SIGHTSINGING TUTOR?
ARCT Harmony is one of three supplementary written courses required to complete an ARCT in performance. The course expands on the concepts learned in Level 9 & Level 10 by adding additional chromatic harmonies such as augmented sixth chords (Germ, Fr, It), Neapolitan Chords (bII6) and common tone diminished seventh chords (CTº7). The use of modal mixture will see students write in major and minor modes simultaneously as well as realize large excerpts of figured bass in keyboard style. A large vocabulary of chord progressions and a masterful command of voice leading is required before entering ARCT harmony as students are expected to compose a short piece of music unaided.
I recommend taking ARCT Harmony first, then ARCT Analysis, and then ARCT History, in that order.
