I've been trying to learn this for the last couple of days. My fingers aren't taking it too well.
Get your amp set to some dirty clean-tone and a little reverb and get rid of your pick.
Here is the first part:
Tune down drop-D (DADGBE)
On this part I'm barring the 5th fret and just moving the barr around. Using my pink on the lowest 7th-fret note then placing my 2nd finger onto the 6 and pulling it off to let the barr do the 5. This kills my hands.
This where the fun starts. Barring the 5th fret again. Hammering on for the small 4-5, 4-6, 4-6 run down the neck then barring the 3rd fret. Ok, this is the part that I can't do.
When barring the 3rd fret on measure 52, ascend up the strings the do the 3-4-3 hammer-on/pull-off. My fingers can't make the stretch. Any suggestions?
I just found something interesting that made this a whole lot easier.
I use a program called guitar rig in my computer as an amp emulator(distortion, effects..) I plug into a pedal-sized pod as a pre-amp then feed the signal into my soundcard(where guitar rig takes over).
I turned the compressor fx on my pod on and all of a sudden not only my tone is better, but this thing is way easier to play! I guess it's taking all of those dead notes from the barr chords and making them louder. lol!
