Hi Gungalley.
First off, sorry about those 'PM's ... I ususally remove them. They don't really mean 'palm mute' in this case. They're there because I wanted the midi to sound like the version I played and that's the only way I know of to easily shorten the ring on those notes in
GuitarPro, which adds them to the image when you choose that function.
I guess you can't see the movie for some reason, or you'd see exactly how I'm playing it. I do sort of palm mute some of those chords, other times I use my finger tips to shorten the ring on those notes I want short.
As for practice, if you can read the tab and notation, just follow that -- it tells you what notes I'm playing and their duration -- and listen to my version for the detail ... simply imitate my version. Take it in small chunks, like one or two measures at a time, then stitch them together ...
Now, I'll get in there and get rid of theose PMs!
