Wow! He played at least seven different styles and approaches in this less than 3 minute masterclass! Then he closes out with the octaves in the right and left hand improv! Super!
They are two very short hits, I remember spending some time when I transcribed it and slowing it down. Then it appeared to my ears as a double chromatic approach. I agree at full speed it sounds just like two Cs
Hi@@LucaDellAnna , Thanks for the response. I have been practicing this solo many times, and I greatly appreciate your transcription! I hear both a possible 2 Cs or two As (E-flat and A being the 3 and 7 of F7).
