I'm new to the whole music game genre. I've done pretty well for myself since the game came out. I'm currently a medium guitarist in the game, and now am pushing/challenging myself on to Hard. I've done OK getting low 80's % as my best scores. A friend of mine told me to slide my fingers over one color so now my index finger is on the red fret rather than the blue. Are there any other tips you guys may have to help me?
