I’ve been obsessed with these two chords lately. The first is a Bb major with a C root, and the second is a C major with a Bb root. C/Bb and Bb/C. The bass moves up from Bb to C, while the top moves down from C to Bb. It has an up yet down feeling.
Halfway between the Lydian and Mixolydian modes, the two chords seem to be of two minds. Lydian in the bass. Mixolydian up top.
Here’s how to play it on guitar.
I would like to see hundreds of songs written with these chords because they’re so damn nice. If you were thinking of write a Mixolydian song with a simple I to VII chord progression, or if you were writing a Lydian song with a I to II, consider combining them both at once to create a mix of Mixolydian and Lydian. Maybe call it: Mix-Of-Lydian.
