something i found that was really important early on in playing and singing, is Foot Tapping. If you are coordinated enough to tap the time out with your foot when you play something, just transfer the foot tapping to keeping time on guitar, and sing over that. after a while, you naturally evolve into playing more syncopated rythms, until it's complex. If all else fails, do what i did, play bass and sing in a band for a while (regardless of your level of guitar playing, being a bassist will give you a completely different perspective and teach team playing and how to be a musician, rather than a guitarist-theres a big difference)

Isn't it funny how most singers sing because they Have To?
