By the end of this lesson, students will be able to:
Describe strategies for modulating to keys not closely-related using pivot chords.
Demonstrate further proficiency in composing and analyzing harmony that incorporates pivot chord modulation.
Harmonize a melody using a pivot chord modulation to a closely-related key.

Closely-Related Keys
Closely-related keys are those within 1 sharp/flat of the original key. On the circle of 5ths, this is the relative major/minor and the major and minor key on the left and right on the circle.
Composition Strategies: Discuss strategies for harmonizing a melody that modulates to a closely-related key. How do you determine where the melody modulates? How do you establish both the opening and the final key?
Online Practice Worksheets for Practicing Harmonization:
Worksheet 1: (See the section "Melody Harmonization") Two harmonization examples in major and minor. (from Fundamentals, Function, and Form)
Worksheet Set: (San Francisco Conservatory)
Worksheet 1a: A longer harmonization example with practice modulating to V.
Worksheet 1b: Composition practice. Given a key and the pivot chord, compose a progression that modulates to the new key.
Worksheet 1c: Melodies for practice with harmonization featuring modulation.
Analysis: Analyze examples from the repertoire in the Anthology section below. Identify Roman numerals, chord function (T, PD, D), pivot chords and keys, cadences, and non-chord tones by type.
Theory Anthology: Modulation: Examples for analysis that use pivot chord modulation to distantly-related keys. See the section "Pivot Chord Modulation (Distantly-Related Keys)."
Aural Anthology: Modulating Melodies: Sight-singing examples with melodies that modulate. Use these as additional examples for harmonization practice.
