16a Discussion - An introduction to mode mixture

Mixing it Up

Simple definition of Mode Mixture:

• Replacing a diatonic chord with a chord from a parallel mode that shares the same function.
• Ex: replacing ii7 with iiø7
• Modal interchange and borrowed harmony are synonymous with mode mixture

“Which diatonic chords are the same between parallel major and minor modes?”

• The V and viiº chords are the same, becuase regardless of the key signature, V and viiº need to serve dominant function.

“How do you get mode mixture to sound good?”

• Smooooooooth voice-leading is key. Chromatic lines will sound good to the ear even if they move through weird chords.

Common Themes of Mode Mixture:

• It is more common to borrow chords from the parallel minor mode when you are in major than vice versa.
• The six chord is the most commonly altered one.
• Borrowing the flat two chord (from phrygian) while in major is so common that it has its own name: a “Neapolitan” chord.
• The reason borrowed chords are used is often to create smooth, interesting bass lines. For example: using a La, Ti, Do bassline in minor.
• Since the V and V7 chords are the same in both major and minor modes, you cannot borrow them. However, you can change between viiø7 and viiº7 chords.
