Sweep Pickin' Practice:



Jason Becker - Serrana (The Real Way!):




There's not much involved with sweep picking...you learn the 3 major shapes, 3 minor shapes, 3 string and 5 string versions and then just play them ascending and descending until you can play them all cleanly, 16th triplets at 140bpm...that's it!!
My old sweep practice routine:
- Clean tone x 30ish
- Clean tone, reverse pattern x 30
- Clean tone, minor version, x 30
- Clean tone, minor, reverse, x 30
- Clean tone, next inversion x 30
- Clean tone, next inversion, reverse pattern, x 30
- Clean tone, next inversion, minor, x 30
- Clean tone, next inversion, minor, reverse, x 30
- Clean tone, third inversion x 30
- Clean tone, third inversion, reverse pattern, x 30
- Clean tone, third inversion, minor, x 30
- Clean tone, third inversion, minor, reverse, x 30
- Clean tone, original shape, 5 string version, x 30
- Clean tone, original shape, 5 string, reverse, x 30
- Clean tone, original shape, 5 string, minor, x 30
- Clean tone, original shape, 5 string, minor, reverse, x 30
- Clean tone, next inversion, 5 string version, x 30
- Clean tone, next inversion, 5 string, reverse, x 30
- Clean tone, next inversion, 5 string, minor, x 30
- Clean tone, next inversion, 5 string, minor, reverse, x 30
- Clean tone, third inversion, 5 string pattern, x 30
- Clean tone, third inversion, 5 string, reverse, x 30
- Clean tone, third inversion, 5 string, minor, x 30
- Clean tone, third inversion, 5 string, minor, reverse, x 30
Then I'd do all that again with distortion, all at 40bpm, 2/3 times a day, for a an entire WEEK.
