On page 45 of Jay Hungerford's Walking Jazz Lines for Bass under the heading "Blues (Ray Brown)." Jay presents 36 bars of what are supposedly a Ray Brown style 12 bar blues. (If this is a transcription of a particular Ray Brown recording, he does not attribute it.)
Anyway, Jay's third line of the second chorus is as attached, below. My question is to the E♮that is in the turnaround at measure 24. The chord is Cm7, yet Jay shows an E♮, not an E♭, as the bass note on the second beat.
Do you think Ray really had a natural E there? If so, is this for tension during the turnaround? Or is it simply a half-step approach to the F, regardless of it not being a note that is consistent with the Cm7 chord? Or is this just a misprint, do you think?
