First of all, thank you for making such a great tutorial.
I've always wanted to play boogie-woogie, but thought it was something only a few talented players could play because it looked so complicated.
But thanks to your detailed explanation of each part, I thought that maybe I could play it, so I bought a piano for the first time in my life.
And this is my progress now.
It's still like baby steps, but it's a big step for me. I look forward to being able to play better.
