Spell and recognize leading tone triads and 7th chords in major and minor keys.
Describe how leading tone chords are typically used in common-practice harmony and how they relate to the phrase model.
Analyze examples from the repertoire that use leading tone chords and apply Roman numerals and functional labels (e.g. T, PD, D).
Compose a chord progression that uses a leading tone chord as part of a tonic prolongation.
Harmonize a given melody using a leading tone triad or seventh chord.

Composition: Compose a chord progression in major and minor. One should incorporate a leading tone triad and the other should incorporate a leading tone 7th chord prolonging tonic. Switch with a partner and have them partwrite your progression in 4-part keyboard and 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, chord function (T, PD, D), cadences, and non-chord tones by type.
Leading Tone Chords: Examples for analysis using both leading tone triads and 7th chords.
