Let’s look at some expensive sounding chords. The extended harmonies in these 2-5-1 progressions can be thought of as poly chords. You might hear this as an A minor on the bottom and a G on the top.
The tritone in the left hand implies the D7 chord, while the right hand plays the surprising Bb major. F minor 7b5 in the left hand, Eb in the right hand. Tritone shell of the Bb in the left hand with a G major chord in the right.
And this Eb tonic has a C minor on the left and an Eb sus2 on top. Happy Chord Day! If you love harmony and music production, check out a Beat Kitchen class and follow us.
