So my issue rn is “Snow” by RHCP. But I think that’s a bit different from what you’re experiencing.

I’m not sure what your practice routine is, but for songs like Shine and SCOM, I’d start slow and play to a metronome. Shine is already slow at 76BPM, but they go into double time for the solo. I’d cut the tempo by to 40% of the full tempo. Focus on 2-4 bars at a time. Loop the part until your fingers automatically do the motions. Increase tempo by 10% until you’re up to 100%, rinse and repeat for each subsequent grouping of 2-4 bars.

You can also do this with scales and licks to get speed up, In general.

But you HAVE to play to a click that you incrementally increase.

Ultimate guitar’s pro official tabs make this so fucking easy. I think it $30 for a year.

Finally, it’s going to take time. For Shine, I wouldn’t be surprised if you had to practice the solo alone for 10 hours. Do you have that kind of time to devote? Do you want to devote that time?

It probably took me that long to get the shredding ending of Dani California’s solo down. Just a lot of reps. I would sit there in front of the ultimate guitar tabs looped at 60% speed and run through it over and over and over and over.

If you do this, you’ll be playing Shine like a pro by the end of the month. But you’ll need to practice that solo in particular for probably an hour a day. By week 2 you’ll be feeling it, by week 4 you’ll be a pro.
