Open G Tuning, Blues, and CT43
Last year I did a few reactions to Alip Ba Ta classic rock videos and people from Indonesia started to come on board in droves so every once in a while I have posted a reaction to songs by Alip Ba Ta. 
I haven't posted a video like that since October 2021.
CT43 is an original blues composition played in open G tuning. 
In this video I show you the open G tuning, play a blues song by one of my favorite guitar player singer/songwriters. (See if you can guess what the song is and who did it.) Whoever guesses correctly first will get a free lesson from me. Hint: I sang two verses of the song but the title of the song doesn't appear in the lyrics until the 3rd verse. ;)
We go over 15 chords that we can use in open G tuning to play blues. There are only 5 shapes but when we move them around in 3 different places on the neck we get 15 different chords. That's the way open position chords that turn into barre chords work.
Comments? I'm going to make another video without Alip Ba Ta in it talking about the same tuning and chords. The original Alip song is rather fun and also short.
