I have learned that to have more in your arsenal makes you a stronger player. Reading notation opens up the world of "studio session" work if you can get it. Loui Conte, Ritchie Gajate Garcia and others in L.A. have learned to read for just that reason to be able to play for movie scores and make the big bucks. Some session players can get up to 3,000 dollars a session .Paulinho Da Costa gets more than any percussionist that has ever recorded and he's on about 7,000 albums on all genres. Reading is only going to make you a better musician. having "ears" to play is one thing and to be able to read is another. The combination of reading and listening is the best combo of course. I strongly believe in "developing an ear" for playing alone and in an ensamble. James Brown does not read music but his ears were made by God......as he tells it.....JC JOHNNY CONGA....WHO CAN ARGUE WITH JAMES BROWN?
