| That all looks pretty much diatonic on A flat, except the last two chords, which are pretty much standard blues tension at the turnaround. The tune is centered on the IIIm; so, you can funk off that root or substitute any of the other diatonic centers. Try running the diatonic series and you'll get the idea. However, the main thing IME for a funk solo is to maintain and develop your rhythmic motif, focusing on space between the notes and syncopated variations. In fact, you have a lot of latitude; you can use quotes, rhythmic licks etc.; but generally in a funk solo, keep it tasty and simple, and try not to play too many notes. Funk is a feel thing first, pyrotechnics second. My <2c. I hope that helps.
Oh yeah, MM is an outstanding reference. |
