this is embarassing. Ive been playing the guitar for almost 2 years and me and my mates decided to make a rock/metal band called kazm(not KAZAM!!!said like chasm)
ok now i can read tab fine and thats great but i hear that it would be better if i could read sheet music.

Is it true that sheet music is better than tab?
If so where can i learn to read it without being knocked down by sites offering to help me read music in 3 hours for a tenner...this gets really annoying, i want free!
follow that above link. go through every lesson three times. practice practice practice.
Learn the theory behind it. Then practice playing/singing from sheet music 10-15 minutes each day, and you should be pretty fluent in a year or so.
