Thank you for posting Part 2. I'll have to watch it again, at least. I enjoyed watching the breakthrough moment at apx 50:00 min - to see then, the rest get worked through, if even for only 10 mins provides a way to self analyze with the inferred tools you see suggested (picking a vowel, siren - then adapt). Possibly more of watching how, in real time challenges being overcome, and re-sung in the new voice proficiency, could be featured more. As well, I really appreciate very much His word, analogously spoken throughout - the purpose of "it", it all in song, His language, of all kinds of music.
