Discussion
Roman Numearl Notation: Why are cadential 6/4 chords not typically notated as I6/4? What does the difference in notation communicate about the function of the chord? Does a cadential 6/4 chord have tonic or dominant function?
Using a Cadential Six-Four: How is a cadential 6/4 chord used in a phrase? Which chords typically follow and precede it? Where does it occur metrically?

Composition: Compose a chord progression in major and minor that incorporates a cadential 6-4 chord. One progression should end with a half cadence, the other should end with a PAC. Partwrite one progression in keyboard style and the other in chorale style. Label the cadence, Roman numerals, and chord function (T, PD, D). If there's time, also compose a melody for each progression. Perform your progressions for the class.
Analysis: Analyze examples from the repertoire in the Anthology section below. Identify Roman numerals and chord function (showing the tonic prolongation at the beginning of each phrase). Also identify the cadence by type as PAC, IAC, or HC. Identify all non-chord tones as P, N, IN, App, E, S, R, or Ant.
