Idiot's Guides - Music Theory
No one likes a know-it-all. Most of us realize there’s no such thing—how could there be? The world is far too complicated for someone to understand everything there is to know. So when you come across a know-it-all, you smile to yourself as they ramble on because you know better.
You understand that the quest for knowledge is a never-ending one, and you’re okay with that. You have no desire to know everything, just the next thing. You know what you don’t know, you’re confident enough to admit it, and you’re motivated to do something about it.
At Idiot’s Guides, we, too, know what we don’t know, and we make it our business to find out. We find really smart people who are experts in their fields and then we roll up our sleeves and get to work, asking lots of questions and thinking long and hard about how best to pass along their knowledge to you in the easiest, most-accessible way possible.
After all, that’s our promise—to make whatever you want to learn “As Easy as It Gets.” That means giving you a well-organized design that seamlessly and effortlessly guides you from page to page, topic to topic. It means controlling the pace you’re asked to absorb new information—not too much at once but just what you need to know right now. It means giving you a clear progression from easy to more difficult. It means giving you more instructional steps wherever necessary to really explain the details. And it means giving you fewer words and more illustrations wherever it’s better to show rather than tell.
So here you are, at the start of something new. The next chapter in your quest. It can be an intimidating place to be, but you’ve been here before and so have we. Clear your mind and turn the page. By the end of this book, you won’t be a know-it-all, but your world will be a little less complicated than it was before. And we’ll be sure your journey is as easy as it gets.

Introduction
Back when I was in high school and college (a long time ago, and getting longer every day), many, if not most, of my fellow stud
ents regarded music theory as only slightly more fun than listening to paint dry. I didn’t share that opinion, and still don’t; I think music theory is interesting and fun and an essential part of any serious music education.
Still, if all you live for is to play your instrument (or to sing) 24 hours a day, taking time out from practicing to move a bunch of notes around on paper might not be tremendously appealing. In fact, I believe introductory-level music theory classes are the second most-skipped classes in college music schools, with only music history classes being less well received. (Some enterprising soul is bound to combine the two classes into a “Theory of Music History”—or “History of Music Theory”—course, thus creating new levels of student apathy.)
I’m not sure why so many budding musicians are so down on theory. Maybe it’s because of the way it’s presented. (Let’s face it: Some instructors can be fairly boring when they present this material, and most music textbooks are stultifyingly dull.) Maybe it’s because of the way music theory resembles sentence diagramming and other dreary grammar-related stuff. I don’t know; maybe to some people, it just seems like a lot of work.
But the fact remains: every musician needs to know some music theory. That’s a bold statement, and one that you might take issue with. After all, you’ve gotten this far in your music studies without knowing theory—why do you need to start studying theory now?
Music Theory Is Important
Most musicians, if they want to communicate with other musicians—to play in a band, or teach them their songs—have to know at least the basics about how music works. These basics—notes, chords, and so on—are what we call music theory.
Notes and chords are the building blocks of the language of music. Music theory defines the many different ways you can arrange those blocks into songs and compositions. Without the theory, all you have is noise; applying music theory, you can create great works of art.
Musicians apply music theory every time they sit down to play or sing—whether they know it or not. When you read a piece of music, you’re using music theory. When you write down a series of notes, you’re using music theory. When you play a chord, you’re using music theory. When you sing a harmony line, you’re using music theory.
Even musicians who don’t have any formal training use music theory. When they put their hands on the piano, they might not know that they’re playing a major ninth chord with the fourth in the bass, but they do know that those notes fit together well, even if they can’t tell you why, or the strict chord construction.
Now, if they did have formal training, they could go beyond just playing the notes to sharing those notes with others. Instead of pointing at their fingers and saying “play this,” they could actually write their notes and chords down on paper, in a format universally understood by musicians the world over. After all, it’s a lot easier to tell someone to play a CM9/F chord than it is to say “put your first finger here, and your second finger here,” and so on.
