Notice both the E natural and Eb is played with the right hand. The highlight of this example is that the left hand is playing an octave bass line G-G, E-E, F-F, F#-F#, G-G The right hand is playing a Gm7 to C7 chords in different inversions and a couple of fills using the G blues scale G-Bb-C-Db-D-F-G Gospel/Blues in G in 6/8. The progression is: G - G7/B - C =C#dim - G7 - E7#9 - A7 - D6 the 1st. time thru with each chord lasting 1 measure. The 2nd time, is the same except for the ending where the G7-E7#9-A7-D6 is half a measure/chord ending on a bluesy run in G. Syncopated keyboard left and right hand parts locked together to produce this funk groove with the right hand playing D13 (C-E-F#-B) to D9 (C-E-F#-A). There is a 1/2 step modulation at the end to the Eb13 before finishing on the D13. A common chord progression in the key of C with a Latin feel. Dm9 (II)-G13(I also play G13b9)(V)-Cmaj9(I)-A#5#9 (VI) There's a couple of passing chords, an Ebmin9 before the Dm9, a Dbmaj9 before the Cmaj9 and a Bb13 before the A7#5#9 spicing up the chords.
