I was wondering recently, whether mixolydian, lacking the lead tone but otherwise being very similar to major (ionic), was a scale we could use for writing whole songs in.
In Jazz theory, the basic chords for a major scale can be built by layering thirds over each tone in the scale. This gives us for C major
For C mixolydian, if we layer thirds, we get
I.e. the Cmaj7's lead tone B is flattened in the mixolydian scale, so there we would get C7 instead of Cmaj7, etc.
Now my actual question: Would it make sense to use these chords to harmonize a mixolydian melody?
