13b9 Chord Progression Drill
In this lesson we expand upon the previous exercises by introducing the b9 chord alteration into the whole step 251 drill. We start in the same position as the last drills and explore a useful formula for accessing the b9 tension in all 12 keys.
What Are Chord Alterations?
Chord alterations include the b9, #9, #11, and #5/b13 and these tensions can be used to add specific ‘flavours’ and ‘colours’ to our dominant chord voicings.

The Formula For Dominant 13b9 Colour
Lowering the 2 middle voices in our right hand is the formula that we must remember to access the 13b9 chord colour when playing a Type A extended 251 progression.
Once we have completed this exercise, we will become familiar with the ‘movement’ or ‘hand gesture’ which is used to access this chord colour in all 12 keys.
