When I listen to the explanation in YouTube clips I understand the theory with the chord changes with the the I, IV and V, turnarounds, adding diminished between the I and the IV. ... however, doing it in real time I just get lost. I think it's just a practice thing. Sometimes with jazz improv I try and just make it up in my head without thinking of scales and chords. That's a bit hit and miss and is usually quite linier. Again, a practice thing.
This is one tutorial I did from Guitar World that I did find useful.
The whole vaccine thing here in AU is a bit of a cluster pluck. The government has done a really good job of keeping the virus out, but have really dropped the ball on vaccinations. So we keep going into lockdowns while it seems other developed countries are starting to open up again.
