BTW did you ever notice that Gospel musicians love to play in mostly multiple flat keys like Eb ---- Db I have a theory about that, whats yours ?
The ones I've seen play are in Gb, as they like to call it. Why? It's the pentatonic scale. They can't play a wrong note with that. But, what's interesting is if you ask them to, most can't play a 'real' song, and they will admit it, even though they can really cook in jam mode.
Also, the Eb blues scale is all the black notes adding A, or Bbb.
