Hey Pete,

What makes that first lick challenging is that you are incorporating picking (both downstrokes and some upstrokes) with a few pull-offs and a hammer-on. If the lick isn't sounding correct, then you must play it slower and figure out where the problem area is.

In learning any new lick, the key is to play the lick much slower than the normal tempo. Once you have the lick at the slower speed, you still must practice the lick several times at that speed, so that your muscle memory will start to become used to the movements.

This is important: always make sure you are playing the lick accurately and correctly at the slower speed before increasing the tempo!! If you don't, it doesn't matter how fast you play the lick, it will never sound correct.

I hope this helps! Let me know how it goes!

Mike
