I need alot of help with very fast galloping. i've been practicing gallops for about 3-4 weeks and i can't get them up to speed with most of the songs i would like to learn.

for some reason gallops came naturally when playing songs like Battery by Metallica, i can play that in my sleep, but when i get to songs like What a Horrible Night by The Black Dahlia Murder. I can never gallop that fast.

Any tips on getting faster?
keep your pick as close to your fingers as possible to reduce resistance and try experimenting with different pick guages
try playing bleed by meshuggah, when ur done with ull be able to gallop anything....

start slow and build up speed
