AP MUSIC THEORY CHAPTER 18 & 19 Modulations

Change of Key, Modulation & Tonicization Change of Key: Shift of tonal center from movement to movement Modulation: Shift of tonal center within a movement Tonicization: Shift of tonal center in a shorter excerpt

Five Types of Key Relationships Enharmonic Equivalent Parallel Relative Closely Related Foreign

Key Relationships Enharmonically Equivalent Keys… Sound the same, but spelled differently C-sharp major: C# D# E# F# G# A# B# D-flat major: Db Eb F Gb Ab Bb C

Key Relationships Parallel Keys… Relative Keys… Major and minor keys with the same key signature the same tonic

Key Relationships Closely Related Keys Major and minor keys with a difference of no more than one sharp or flat

Key Relationships Change of Mode/Mode Mixture Change from one key to its parallel

Five Types of Modulation Sequential Common Tone Common Chord Monophonic Direct/Phrase

Common Chord Modulation • Smooth modulation using 1 or more chords that are common to both keys • “Common Chord” serves as a pivot • Most common modulation

Sequential Modulation • Modulation through a sequence • This will tonicize a different key • Common chord is often found in this modulation when analyzed

Common Tone Modulation • Like “Common Chord”, but instead the modulation pivots on a “common tone” • “Common tone” is often isolated and makes it obvious

Monophonic Modulation • Modulation that is carried out by a single line of music (monophonic) • Emphasizes tones found in 2 nd key, not 1 st key

Direct Modulation (Phrase Modulation) • Not smooth modulation • Occurs often between phrases (AKA Phrase Modulation)
