For those of you studying your guitar shred, here is some new material you need to spend some time on. Bach’s 15 inventions. If nothing else you need to learn Invention # 4 in D minor. The first two measures alone make an awesome picking exercise, But on top of that, they’re great tunes.
Learn at least the right hand part of the inventions. (the top line) And learn it in all positions. This can be a time consuming process, but it is well worth it if you do it. And if you are feeling even more ambitious, record the right hand part and practice the left hand part along with your recording.
Getting together with a friend to jam on the inventions is a great way to improve. You will really have to be in sync with each other or they aren’t going to sound good. They can be technically challenging so go slow and take your time.
Players like Paul Gilbert, Steve Vai and Mike Stern have all mentioned practicing bach. That should be enough to let you know that if you are serious about guitar shred, you need to learn some or all of these.
