Chromatic Exercises
Probably the (or one of the) most important exercises for shredders are
chromatic exercises. They help develop co-ordination between the picking
hand and the fretting hand. They are best practiced using a metronome
(extremely useful tool if you want to be a shredder!)
Chromatic exercises help develop strength in all the fingers. I remember when
I first started getting into shred, my first milestone was when I practiced chromatic
exercises for about 8 hours straight one weekend. The improvement was quickly
noticeable. Before then I just couldn't play the chromatic riff to Master of Puppets
by Metallica at any sort of quick speed with alternate picking. Afterwards, it felt so much
easier and I found I could do it straight away!
My favourite chromatic exercises are the ones which work with 4 notes per string,
going up the strings from the bass to treble strings (E to e) and back down again.
I do them at the first fret, then second, up to the 12th fret. This also develops
stamina, and this little variation helps stop you getting bored. One thing to note with
these exercises; make sure you aim for accuracy before speed. If you teach your
hands to remember them incorrectly, that's how you will always play them, and it
becomes much harder when you'll have to re-learn them. Start of at an easy speed,
and gradually increase the metronome until you think you've reached your limit.
Turn it down a few b.p.m, and stay at that speed until it becomes really easy for
you. Repeat that method again and again and you should increase speed quite well.
Always use alternate picking! (up/down/up/down)

Chromatic Exercises to Use:
I mostly use these patterns whilst practicing or warming up, but feel free to vary the
patterns to challenge yourself.
