"Just because you have developed the craft on your instrument doesn't mean that you don't have the ab..." — John Petrucci

2112' basically set the course for my musical career and how I approached Dream Theater.

Before you can apply chromatic ideas to scales and arpeggios, you have to get the chromatic scale itself under your fingers. You should learn it up and down the neck, and become comfortable with the fingerings.

Before Dream Theater took off I used to teach a lot, and one of the things my students often asked me was how to apply the chromatic scale to practical playing situations. You see, their other teachers would give them chromatic warm-up exercises without providing any explanation of how important and versatile this scale actually is.

A violin neck is much smaller than the guitar's, so it's much easier to play wide intervals on one violin string. On the guitar, you really have to stretch to play them.
