In this quick music theory lesson, we're going to take a look at the major scale formula. The major scale is the foundation for almost everything in western music, so it's very important to take the time to gain a solid understanding of it.

The major scale formula is simply a sequence of whole-steps (W) and half-steps (H). A whole-step is two semi-tones or frets and a half-step is one semi-tone or fret. You'll want to make sure you take the time to memorize this sequence since you'll be using it a lot in your time learning to play the guitar.

Major Scale Formula

Once you've got the sequence memorized, you'll want to apply the major scale formula to a key. In the video, we'll be doing this with the key of G major. Practice applying the formula to other keys by adding them to your daily practice time.
