Hi @Jacklr
Below are my thoughts - influenced by my experiment of spending a year on one very difficult Yngwie lick and eventually being able to play the Steeler descending fours at Yngwie speed. Your way may be different to mine though
a) It is great you are on taking on an Alcatrazz solo! They are hard to play if you want to play them with “Yngwie Sync”
b) 190bpm for extended reps with high accuracy is challenging - the good news it is a repeated 6 pattern
c) it is not challenging for Yngwie - look at how easily he manages it in the live video!
d) breaking it down to just focus on the first set of 6’s at his speed and sync is how I would start
e) I would ditch the metronome as others have suggested - treat it as a burst lick
f) to get it to sound like Yngwie means very, very accurate hand sync (slow his to 25% and you will hear it)
g) I tested my practice sessions by slowing down via the software my recorded takes to see if I was hitting “Yngwie Sync”
h) Record all your takes and review - if possible get the Yngwie solo into your DAW and test yours against his
i) Yngwie is naturally significantly faster than most players - to get into that zone I had to really PUSH
j) I was continually playing it slower than Yngwie - even when I thought it was as fast - so I started singing the lick to help me get the speed - so for your lick “meedly meedly meedly meedly” etc as fast as he plays it to help psychologically get the speed - this really helped at the end
k) elbow mechanic is where I get extra speed if my wrist finger motions aren’t cutting it - then I reintroduce them if sync is faltering
l) experiment with pick escapes
m) this could take you a while to get it to Yngwie level - it took me a year of intense practising the one lick to get the descending fours happening at 190bpm with Yngwie sync- so don’t give up - make it fun
n) you can do it!
