By the end of this lesson, students will be able to:
Explain how six-four chords typically function in the context of common-practice Western art music.
Describe standard voice leading for six-four chords in common-practice repertoire.
Recognize examples of passing, pedal, and arpeggiating six-four chords in examples from the repertoire and label them using figured bass and Roman numeral notation.
Compose a harmonic progression that uses each type of six-four chord to prolong tonic, dominant, or predominant harmony.
Harmonize a given melody using a passing, pedal, or arpeggiating six-four chord.

Six-Four Chord Function & Voiceleading: What are the 4 different types of six-four chords? How do they function within the context of the phrase model? Describe the bass movement for each chord.
What does the voice leading look like?
What are a few common progressions discussed in the reading?
Why do you think the pedal six-four is also often referred to as the "neighboring 6-4" chord?
Practice Worksheets:
Worksheet 1: Partwriting and analysis with passing, pedal, and cadential six-four chords. (Open Music Theory)
Worksheet 2: Harmonic analysis, labeling 6-4 chords by type. Examples by Louise Farrenc, William Brady, Clara Schumann. (Solution available here). (Diverse Music Theory)
Worksheet 3: Complete 4-part settings of examples featuring six-four chords given the bass, soprano, or outer voices. (San Francisco Conservatory)
Worksheet 4: Analysis of short excerpts by Beethoven and Brahms. (San Francisco Conservatory)
Composition: Compose three 4-bar chord progressions. Each should use a different type of six-four chord (passing, pedal, or arpeggiating) to prolong tonic, dominant, or predominant harmony. Partwrite the progression in chorale or keyboard style. Label the cadence. Identify Roman numerals and chord function (T, PD, D) below the staff. If there's time, also compose a melody for the chord progression.
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.
Six-Four Chords: Examples for analysis that use passing, pedal, arpeggiating, and cadential six-four chords.
