Ok so making some progress. Surprised once I got over the weirdness of starting the new string with a downstroke how quickly I could start to adjust. I have been alternate picking for years so not a noob. So you can adjust quickly.
I still need to polish though - particularly getting the first 3 notes before the jump to the high E.
It is very easy to play the 12-14-16 accidentally as “pick (down)-hammer-hammer” as you get ready for the down stroke on the high E (12th) as opposed to “pick (down)- pick (up)- pick (down)” then high E 12th pick (down)
Recapping this is the lick I am working on:
Then the next part is working out where Yngwie used legato through the turnarounds in this lick! Oh dear LOL. I was trying to follow what Troy was telling me about the escape strokes - but am a bit lost trying to apply it to this turn around.
Anyway thanks all for the input. Have got a lot out of this thread.
