This ultimately is the secret that unlocks outstanding lead guitar playing, great songwriting, and great musicianship in general. I have cited techniques used by rock and blues guitarists Kirk Hammett, Zakk Wylde, Eric Clapton and BB King, but a point I wanted to arrive at in that context is that each and every great guitarists (and great musicians, for that matter) understand music theory; guitarists who can play at that level understand what they're doing, in other words. Now, a few folks might say, "Well, yeah, but guys like Eric Clapton, Eddie Van Halen and Alex Lifeson are self-taught players and have never had a conventional guitar lesson or formal guitar instructor". That would be accurate, but rest assured, these guys unquestionably know and understand their music theory; it would be inconceivable for them to play the way they play if they did not.

What appears to be the common opinion in the music world is that it takes some arcane, cryptic, not-of-this-earth ability to interpret music and music theory when really it does not. For instance, lead guitar playing is broadly speaking going to sound good so long as the notes that are being played are the same as, or like to, the notes in the underlying chords of the tune itself. Easy concept, isn't it? Nonetheless, it calls for a great combination of chops on an instrument and knowledge of music theory in order to accomplish that concept in practise. Knowing music theory, in my belief, is so crucial that I am unwilling to take on a guitarist as a student if the student is unwilling or maybe too lazy to learn it, for whatever reason. What ultimately happens is that these students might get to the point of being able to play many musical compositions but never come to understand why a piece of music sounds great or how chords, scales, and keys all accommodate collectively to produce whatever sounds they're hearing or playing. Ultimately, the musician who does not know music theory is only going to get so far.

In discussing crucial music theory, what springs to mind is, first of all, a thorough knowledge of the major scale and its 7 degrees, the stacking of the major scale in thirds to make chords and major keys, the relationship of other scales to the major scale and how those scales are spelled out, the understanding of intervals (very important), and an understanding of modes and modal structure (which isn't as tough as it appears, given the right information). The complete key to understanding music theory, in my opinion, is to understand the Circle of Fifths (Fourths); the reason it has this name is because the circle ascends in perfect fifths whilst going clockwise around the circle and in pure fourths when going counterclockwise. Once a musician realizes this circle and how it works, that musician has finally made it.

A short note on the "get-chops-quick" methods on the Internet today: I'd have to say that, based on the ones I've seen, that I am skeptical with regard to their claims. They lavishly promise all these lightning speed results without even knowing if the guitarist who is considering buying their method can play even a simple bar chord! Now, unless the beginning guitarist is descended from Superman and has hands of steel, playing a bar chord for the first time (such as F Major) is going to hurt; it is going to be painful. Matter of fact, I've had students give up and quit right in front of me because they felt that playing guitar hurt their hands too much. Therefore, is someone who is still adjusting their hands to the guitar going to be able to play like Jimi Hendrix in one week? I don't think so.

This simple approach outlined here is conceptually simple, but not easy. Good things sometimes take time. It takes a few more words and a bit more effort to explain concepts clearly. My hope is that the information in this article will help make your musical experience less mysterious and more enjoyable, and that the next time you go into a music store or on the Web looking for guitar books and methods, you'll know exactly what to look for.
