Music Theory – Level 1

Welcome to the Music Theory Course! The lessons contained here are meant to give you background in the basics of music theory so that when you work through the various courses found on the site you will already have the basic tools you need to improve your musicianship skills. This Level One course will cover the following:


1. Treble and Bass Clefs

2. Note Names on the Staff

3. Ledger Lines

4. Octave Relationships

5. Chromatic Scale

6. Key Signatures

7. Diatonic Notes

8. Intervals


You will also be given quizzes after each lesson to test your comprehension. Some information, like the note names on the staff and ledger lines, will take more work to master than simply completing a few quizzes in this course. In order to help you master the names of the notes on the staff and ledger lines we have created the Note Recognition Course which we highly recommend you take after completing this level of the Music Theory Course. As you can see, this course also covers intervals, which again, you will need much more work on in order to truly master. In order to help you in this task we’ve created a course called Interval Recognition. This will help you to memorize intervals in all keys and as you move through the various levels, to memorize all possible intervals in all keys as well as intervals with chromatic alterations and intervals that are larger than an octave.


One common mistakes students make is to believe that having a cursory understanding of music theory is enough to be a competent musician. This is completely untrue! You need to understand music theory the same way you understand the language you speak, so that no matter what key you are in or what musical situation you find yourself in, you will be able to instantly know the theoretical relationships that are at play in that situation. Working through the Music Theory, Note Recognition, and Interval Recognition Courses on this website will get you there, and prepare you for any musical situation. It is of course important that you apply the knowledge you learn in these courses to real music, and to playing situations. We recommend you do this by analyzing the songs you want to learn, learning to read music on your instrument and making sure that you understand the music theory relationships behind everything you learn on your instrument, such as scales and arpeggios, so that you are not just memorizing patterns.

With all this in mind let’s get started on improving your music theory knowledge now!
