Learning Outcomes
By the end of today’s session, students will be able to: 1. Identify and construct chord scales for minor key chords and progressions 2. Identify and construct chord scales for blues chords and progressions 3. Revise chord scale construction considerations.
• Because of the different configurations of tonic minor key scales there are more options for diatonic minor key chord scales
• Diatonic chords in minor keys use diatonic chord scales
• Avoid note criteria is the same (with the exception of Im7 dorian)
ACTIVITY:
• Construct complete sets of diatonic chords for the following minor keys:
• C natural minor • C harmonic minor • C melodic minor • C dorian

Observations
• Chords with diatonic orientation use diatonic non-chord tones
• Dominant chords with expected resolution down a perfect 5th use some form of mixolydian
• Dominant chords with expected resolution other than down a P5th use a lydian b7 chord scale
• Basically, if the root of a chord is diatonic, think diatonic for the chord scale construction
• The diatonic pitches associated with minor keys/modes include the natural and raised 6th and 7th of the key.
Blues Chord Scales
• The chord scales common to blues harmonies are constructed using chord tones and pitches from the blues melodic scale (the minor pentatonic scale)
