Learning music theory can be a daunting task for many beginners, especially when it comes to constructing scales. However, in this video tutorial, you will learn a simple yet effective method to construct major scales starting from any note in all 12 keys.

This tutorial, presented by Buster Birch, a professional musician and music teacher with over 30 years of experience, explains how to use intervals to construct a major scale and why certain notes are in the scales while we label them the way we do.

The tutorial also covers how to apply the same simple method to construct seven of the most essential scales that you need to know and be able to do that in any of the 12 keys, starting from any notes.

To get started, all scales are constructed using a series of intervals. The sequence for a major scale is tone-tone-semitone-tone-tone-tone-semitone. This sequence gives us the DNA code of the major scale. Essentially, if you start on any note and play that sequence of intervals, then what you'll get is the major scale of that starting note.

Buster emphasizes the importance of listening to the sound of the scale, not just memorizing the sequence of notes. By doing so, you can learn the sound of those scales, not just the maths. This is why doing it at the piano is so good because you can learn the sound and feel of the scales.

Each type of scale has its own DNA sequence, which can then be transposed to all 12 keys. As an exercise, try to construct a major scale from each of the following starting notes.

By following this simple method, you can learn to construct major scales and other essential scales with ease. With practice, you can work in any key that applies to all 12 keys. So, if you're a beginner or someone who's struggling with music theory, this tutorial is a must-watch for you. It's an excellent resource for anyone who wants to learn music theory with a beautiful logic that oversees the whole thing.
