This is a common problem... Since SO MANY of you are having this problem I have turned this from a response to a blog. I will add more tips daily as you guys ask more questions. If you have a question on how to do something post on here and I will comment back in a new blog. :D
The question:
Learn this NEW hand position...
Move your hand down so your pinky is sitting on orange and your index on red. It's easier to stretch your index to green than it is to stress out that poor pinky. Once you are comfortable with this position the next step is to learn to transition from the index on red/ pinky on orange to the index on green/ pinky on blue positions when necessary so that you can use your two strongest fingers (index/middle) to hit whatever notes are more prominent during that section. If you see a lot of green/reds approaching move your hand to the first position (g/b) and if you see a lot of yellows blues and oranges move it to the second (red to orange) The goal is to use your pinky as little as possible however shifting your hand around as needed to try to hit a majority of the buttons using only your index, middle and ring fingers.
Trills (a series of back and forth notes) that consist of Oranges and blues should be hit using your index/middle or middle/ring fingers since they're stronger and easier to control, however it's tricky to shift your hand down that fast then repositioning it to the red-orange position without missing notes.
Another method is to learn "tapping" videos can be found on youtube. This technique is when you strum with your right hand then bring that hand up to the frets using it to tap on the blue/orange buttons during hammer on/ pull off and slider sections. This is especially useful for songs like "Spiderwebs" on GH: World Tour, "Our Truth" on GH: World Tour, and "Through the Fire and the Flames" GH3 as well as other songs of the like.
I want to make a youtube "HANDS" video for you on a song that you have trouble with so you can see what I'm talking about. I'll try to do a picture in picture if possible so you can see how I shift my hand. Please send me a message with a song you'd like me to show you the technique for. :D
I hope this helped. If not or if you need further explanation let me know. :D
I just started getting into GH/RB and I can't seem to get Orange Fretting down, I think my hands are stupid. Any advice before I go lefty?
