Robyn - There's -nothing you can't learn to play-!
The trick is to get it down so you can play it cleanly at a slow tempo. Here's what I do when I want to learn something new: (You need a plan of attack! Use this...)
1. Break it down into small sections. Start with the first 4 or 5 notes. Once you get it, move on to the next section, and so on and so on.
2. Play it slowly at first. If you go for speed immediately you'll end up getting frustrated and quitting. How can you play something fast if you don't know how to play it? So go slow at first. Once you get it down where you can execute it clean at a slow tempo, it's easy as pie to very gradually increase the speed.
3. Don't move on to the next music section until you've mastered the one you're working on. This one is just good horse-sense. If you move on to the next section before getting the one you're working on, down, every time you get to that section, you'll screw up and throw yourself off. Four/five notes at a time until you can nail it. Then... move on. (Learning anything new takes discipline!)
Speed will come! With repetition and practice you'll soon be playing the patterns 'up to speed.' Frustration comes from skipping steps. Trying to tackle too much, too soon. Slow and steady wins the race!
Stanton plays the LLRLRLRR slowly a couple of times. Start from there. Follow the steps... take it apart and start slow, and success is guaranteed. All a matter of how bad you want to learn how to play that stuff. But you -can- do it.
