By the end of this lesson, students will be able to:
Explain the concept of tonic prolongation and describe how V6 and inversions of V7 may be used to prolong the tonic function.
Summarize the 4 most common basslines used for tonic prolongation with dominant chords.
Analyze examples from the repertoire and apply the phrase model to describe the role of each chord in the progression.
Compose a chord progression that incorporates inversions of V and V7 with a tonic prolongation at the beginning of the phrase.
Harmonize a given melody using a V6 or inversion of V7 as a form of tonic prolongation.

Figured Bass
Having trouble remembering the figured bass for the different inversions of V7? The numbers descend: 7, 6-5, 4-3, (4)-2. Check it out:
Root position (root in the bass): 7
1st Inversion (3rd in the bass): 6-5
2nd Inversion (5th in the bass): 4-3
3rd Inversion (7th in the bass): 4-2
Or, you can remember the Music Theory Hotline: (664) 765-4342.
The area code is the inversion numbers for triads in 1st inversion (6) and 2nd inversion respectively (6-4)
The next 7 numbers are the figured bass numbers for the 7th chords.

Review of Bass Scale Degrees: What is the scale degree in the bass for each of the following Roman numerals: I, I6, V, V6, V7, V6/5, V4/3, and V7.
Where do V4/2 chords tend to resolve? What about V6 and V6/5 chords? Why?
T-D-T Prolongation Basslines: The Open Music Theory reading outlines 4 common basslines that are used for prolonging tonic harmony at the beginning of a phrase. There are 4 other basslines that may also be used that also incorporate passing, neighbor, or incomplete neighbor motion in the bass between 1 and 3. What are these basslines? and what are the Roman numerals that accompany them?
Practice these basslines with this Quizlet set.
Then, compose a 4-bar chord progression that uses at least 4 of these tonic prolongations.
Practice Worksheets:
Worksheet 1: Partwriting and analysis with V6 and Inversions of V7. (Open Music Theory): PDF | Docx | Recording | Score
Worksheet 2: Practice resolving inversions of V7 chords to tonic. (Turek, Theory for Today's Musician, see p. 159, 1E) [Available online through the library here].
Worksheet 3: Harmonization with I6 and V6. (San Francisco Conservatory)
Worksheet Set for practicing with Inversions of V7: Short harmonizations, Longer Harmonizations, Analysis (San Francisco Conservatory)
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.
