Neo Soul is not a genre you learn from a book—it is a feeling you coax out of the piano by relaxing your wrist and trusting the "crunchy" notes. The difference between a pop pianist and a Neo Soul pianist is simple: courage . Courage to play the 9th and the 3rd together. Courage to let the rhythm breathe.
