No error, it is correct! It’s a 3 note enclosure resolving to C. G# and A can’t be the lower portion of the enclosure to C. The lower in this case has to be a double chromatic approach because the upper is a single diatonic approach. Please review p.79 in the lesson book for definition and examples of 3 note enclosures.
Sorry, I didn’t know you were referring to the video. I just checked it, and you are right… I did play what you said. Thanks for pointing that out! You are the first one to notice that error after 5 years of having published it! At least someone is paying attention.:)
I will probably correct the written portion, as it is much harder to redo the video.
In my opinion, the most important is the concept and you explain it very well. The two options sounds well. Maybe in the video is more deltabluesy 🙂 and in the score is more bebop. I only say it for informe about it. (Sorry for my english 🙂
