It's the obvious easy and simple fix.
Dennis don't read, Buddy didn't, but there are no "two school." If you go to school you learn how to read, because it's the universal way to learn and communicate.
Not beaing able to read is not a badge of honour. For some it's how they grew up, how one would learn a certain tradition, etc...
Just like if you learn to read, write and understand the English language all the knowledge in the libarary is then available to you, so is it also with learning to read music.
Learning to read music and count subdivision is the single best ting, especially if you're self taught, thing you can do to understand rhythm better.
There are some prodigies out there with their own way. The late Allan Holdsworth and also Chick Corea are among them, but most of the time it's just an excuse.
