Week 4
Contiguous Dominants and Related IIm7 Chords
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
UsageContiguous 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
Activity
