Sorry if this has been beaten to death. On the Kind of Blue album, what is Paul Chambers playing in bars 5 & 6? I hear him taking the pattern G-D-E-D-F-D-E-D from bars 1 - 4 and moving it to the IV chord (C7). But I find a lot of instruction saying to hold the I chord pattern over the IV chord as it is actually a Gm7 not a C7. When I try to play that with the record it doesnt sound correct. Forgive my ignorance in advance, I"m a jazz novice.
