By the end of this lesson, students will be able to:
Aurally identify examples of tritone substitution in examples from the repertoire.
Transcribe the melody and chords for short examples that include tritone substitutions.
Sight read, improvise, and transcribe rhythms that incorporate beat notes other than dotted quarters in compound meters (e.g. 6/4 and 9/16).
Sight sing and improvise melodies that incorporate tritone substitutions and demonstrate further proficiency in sight-reading melodies that modulate.
Explore chord progressions with tritone substitutions:
Chord Player: Practice building chord progressions in Chord Player that use tritone substitutes for V7 and V7/V and singing along with an improvised melody to get the sound of these chords in your ears. Here's a looped progression to start with: I - ii7 - Sub(V7) - I (in A major: A - Bm7 - Bb7 - A).
Handout: Tritone Substitute Handout (Louden)
Melodic Improvisation (Tritone Substitution): Compose a progression that incorporates a tritone substitution (or pick one from the anthology). Sing through arpeggiations of each of the chords, then improvise a simple melody over the chord progression without using a chord grid (but visualizing it while you sing). Create a backing track using an online chord player like Chord Player, Musicca Chord Player, or ChordChord to fit your progression. Be sure to discuss tendency tones and chromatic scale degrees!
Melodic Sight-Reading: Continue sight-reading melodies in the section "Closely-Related Keys."
Rhythm Sight-Reading: Sight-read rhythms in the section "Compound Meters."
Theory Anthology (Tritone Substitution): Listen to examples in the section "Tritone Substitution" and identify where you hear a tritone substitution. Select a few examples to transcribe; transcribe the melody and chords using both Roman numerals and chord symbols.
Continued practice listening for modulation:
Aural Anthology: Continued practice listening for modulation and identifying keys. See the section "Modulation ID."
Theory Anthology (Modulation): Listen to examples that modulate in the sections "Direct (or Abrupt) Modulation" and "Pivot Chord Modulation). Identify the key that the selection modulates to, then transcribe the melody and harmony.
