What is Modal Interchange?
The practice of borrowing chords from a parallel key or scale.
What difference does Modal Interchange produce?
Different combinations of whole and half steps, although it starts on the same pitch.
MI stands for _____ _____.
Modal Interchange
What effect does applying Modal Interchange have on a phrase?
It varies the color of the diatonic phrase.
Give an example of how a C major phrase might be reharmonized using Modal Interchange.
By using chords from C natural minor, C harmonic minor, or C melodic minor.
State a basic tenet of Modal Interchange.
Chords created from parallel scales may substitute for each other, melody permitting.
Name three MI substitutes for a Imaj7, the derivation of each, and their available MI tensions.
1. Cmi7; natural minor; 9,11
2. Imi6; melodic minor; Maj7, 9, 11.
3. Imi(Ma7); melodic minor; 9, 11, 13.
Name two MI substitutes for a IImi7, the derivation of each, and their available MI tensions.
1. IImi7(b5); Aeolian or harmonic minor; 9, 11, b13.
2. bIIMaj7; Phrygian; 9, #11, 13.
Name an MI substitute for a IIImi7, its derivation, and its available MI tensions.
bIIIMaj7; Aeolian; 9, #11, 13.
Name two MI substitutes for a IVMaj7, the derivation of each, and their available MI tensions.
1. IVmi6; Aeolian or harmonic; Maj7, 9, 11.
2. IVmi7; Aeolian or harmonic; 9, 11.
Name two MI substitutes for a V7, the derivation of each, and their available MI tensions.
1. V7(b9); harmonic; b9, b13, (#9 optional)
2. Vmi7; Aeolian; 9, 11.
Name an MI substitute for a VImi7, its derivation, and its available MI tensions.
bVIMaj7; Aeolian or harmonic; 9, #11, 13.
Name an MI substitute for a VIIdim7, its derivation, and its available MI tensions.
bVII7; Aeolian; 9, #11, 13.
All MI substitutes are _____________, but related to the original key.
nondiatonic
In what other situation can MI be used besides substitution?
Linking two diatonic chords
When using MI as a link between two diatonic chords, what type of function can the second diatonic chord assume?
that of a target chord
Which type of root motion is typical when reharmonizing with an interpolated MI?
strong root motion
The MI chord inserted between two diatonic chords can be thought of as _________.
interpolation
Strong root motion guarantees which quality present in all effective cadences?
contrast
Strong root motion ensures at least _____ new chord tones in each successive chord.
two
What effect do new chord tones have on the listener?
They tend to create more interest.
Name four situations in which MI can be used.
1. To follow and return to the same diatonic chord (color variant).
2. To link two different diatonic chords.
3. To move from one MI to another before returning to a diatonic chord.
4. To replace a diatonic chord with an MI chord.
What's the downside of overdoing MI?
Might create a key change or ambiguous tonal center.
When applying MI, is there a neeed to maintain similar harmonic function? Explain.
Not necessarily. The goal of MI is to expand the harmonic color of the phrase.
What effect would maintaining harmonic function have on an MI phrase?
Possibly make it sound less colorful.
Maximum number of MI chords used before returning to diatonic chord.
Three MI chords.
MI chords generally lead to diatonic chords with this type of root motion.
Strong root motion
