Reading music is one of the most difficult things to learn , and get good at, as such it is one of the best things you can do. Not only will it improve your rhythm but WILL make you a better player all around. It is not easy and only very few players will ever be able to read music as well as they read a book or magazine. But in the Tablature age it has become a "lost" art , so to speak.

If you are thinking about learning to read music for guitar , DO IT! It may be disheartening and frustrating at first , but as with all worthwile endeavors, The payoff is invaluable!

Good Luck
