Theory 1, 2, 3: Easy Concepts -- Half Steps and Whole Steps

In my last “Theory 1, 2, 3” column I discussed the scale numbering system that gives us our “thirds,” and “fifths” and all that. If you missed that column, you can find it here.

In this column I’ll explain three simple concepts to help you understand what guitar players mean when they talk about half-steps and whole-steps.

It’s not hard to grasp, so let’s go.

Theory Concept 1: What are “Steps” in the First Place?

Steps -- as we talk about them in music -- are simply the distance between two notes. We usually hear musicians talking about half-steps and whole-steps, though sometimes we might hear someone say “one-and-a-half steps” or “three steps,” referring to larger distances between two notes.

We can also define scale patterns with formulas that spell out the succession of half-steps and whole-steps that make up that particular type of scale. A minor scale follows a different pattern of half-steps and whole-steps than a major scale, for instance. The Mixolydian mode follows a different succession of half-steps and whole-steps that some exotic scale from the Middle East.
