Mario,

This is really interesting. The changes Db7 to Emi6/C (where you're playing Db and C on the bass) hides the dissonance C# (the 6 in Emi6) on top of the C bass. BUT - and this is the really clever thing - only the C# differentiates Emi6/C from Cmaj7. In the key of C, Emi6/C equals Cmaj7b9, which is a pretty funky sound. But played by the bass, the C covers both both possibilities.

Damn! That's clever. Good guitar sound, intelligent ideas on these unfamiliar changes. And you play sax too?

It isn't a blues, but I wonder what people on the street (a la Jay Leno) would say if you asked them to define "the blues." As in, "Excuse me, sir, can you tell me: In music, what does 'tbe blues' mean? My money says not one in a thousand.
