When you start Expert there are alot of slides like in Cult of Personality. Only use one finger and slide it across the neck in the direction accordingly. This hint can be really useful for Raining Blood on the mosh part.

When you are just starting hard mode it is sometimes difficult to slide your hand to the orange button. I know some people who slide from orange to green, but that doesn't work for me. I slide from green to orange. Anyways, when you are sliding let go of the buttons, don't stiffen up your fingers or it will be really hard to slide over.

As You Probably Have Noticed, In Some Songs, You Will Come Across A Line Of Colours Going Up As In Raining Blood, Well 1 Easy Way To Get These Is To Use 1 Finger, It Easy To Do, Just Slide Your Finger In The Corresponding Order And Strum Only Once.
Most Of You Reading This Are Probably Thinking (YH WE KNOW) But Ive Come Across Some Right Weak People Online Its Not Even Funny.

If you want to play Guitar Hero 3 with the Wii-Mote heres how.

These are what the wii remote buttons cordinate to on the guitar:

Red- The right arrow on the D pad
Yellow- The A button right below the D pad
Blue- The 1 button below the A and above the 2
