Week 3 Contiguous Dominants and Related IIm7 Chords

The Plan for Today

¤  Review Dominant 7th Chords without Dominant Function

¤  Contiguous Dominants and related IIm7’s

Contiguous Dominants

¤  Dominant 7 chords based on deceptive resolution

¤  Contiguous dominants move upwards to other dominant 7 chords in a very specific pattern

¤  Typically, contiguous patterns move: ¤  Up in ½ steps

¤  Up in whole steps

¤  Up in minor thirds

Usage

Contiguous dominants are used:

¤  To delay the diatonic dominant or related IIm7 from below

¤  To create transitional modulations

¤  To extend a cadence from V7

¤  As an alternative to extended dominants

¤  To harmonize static melodic phrases or melodic phrases based on sequence

Contiguous up a half step

¤  Melody is static

¤  Chord scales: ¤  Related IIm7: Dorian ¤  Dominant 7: Mixolydian

¤  The ½ step pattern is in control

¤  Descriptive analysis necessary (contiguous - - - - - - - - - - -)

See page 44 of your Harmony 4 text

Contiguous up a whole step

¤  Melody sequences in whole steps

¤  Chord scales: ¤  Related IIm7: Dorian ¤  Dominant 7: Mixolydian

¤  Whole step pattern controls the progression

¤  Descriptive (contiguous - - - - - - - - - - -)and Roman Numeral analysis required

Contiguous up a minor 3rd

¤  Melody combination of parallel and nonparallel melodic transcriptions

¤  Descriptive (contiguous - - - - - - - - - - -)and Roman Numeral analysis required

¤  Can be used as a transitional modulation

¤  Often used in be-bop
