Besides my rant on how people get things wrong with Music Theory this video is also on some of the things that you are missing if you don’t use music theory right or forget to check out important parts. When you study Jazz or Jazz Guitar then music theory is a part of what you need and what you want to learn, but you want to go about it the right way.
Most of the things I talk about in here are mistakes or problems that you run into if your approach to music theory is very superficial. Hopefully I also manage to give some pointers to a better approach to learn and use music theory so that it is actually useful for you.
Do you make these mistakes? Do you know other things that mistakes that are common?
