Peter,
Love that joke..
If Ya can't keep a good Dorian Mode down, "So What"? Beyond chords, its the melodic phrasing over them, seeking the harmonies, tension & resolution like a classic Bach Chorale, its the timing & techniques combined that can be appreciated, though one need not know the words, scatting over them, its the notes man,.. most that play by ear know when it works, before they find the theory to support it, Miles down the path... good players appreciate some, but little that they fly over on way to a number.. of favorite things
