Music makes the world go around, but do you actually know what it is? To really understand music, here are some of the best ways to learn music theory online for free.

If you love music but you never learned music theory, you're doing yourself a great disservice. The more you understand the basics, the more you will appreciate your favorite songs and artists.

Do yourself a favor and use one of these great sites to learn a little bit more about what makes music what it is.

1. Ableton's Interactive "Learning Music" Course

Ableton's Learning Music interactive online course is a free way for beginners to learn about music theory

If you know nothing about music theory, this is the place to start. Ableton, a maker of musical instruments and a community for artists, created this course specifically for beginners to learn music theory for free.

The course takes you step by step through the different stages of making music. It'll teach you the differences between drums, bass, chords, and melodies, and teach you the basics of beats, notes, and scales.

The whole exercise is interactive, which is great since you are learning by doing. Once you finish with the course, you can go on to advanced topics like major and minor scales, triads, and so on.

Ableton's course is noteworthy for how easy to understand it is, and how quickly you will learn the nuances of music theory. And all you need is a web browser, nothing more.

2. LightNote, the Most Gorgeous Site to Learn Music

Lightnote is a beautiful web app to learn the basics of music theory

Learning music is not just about what you read, it's also about what you see. LightNote is the most beautiful site to learn the basics of music theory.

It's a step-by-step tutorial to understand sound waves, harmony, scales, chords, and keys. The entire course is presented like an FAQ, answering the common questions that a beginner will have.

For example, while teaching harmony, it plays two pieces of music and asks why one sounds good while the other bad. And then it explains the answer, followed by a short test to see if you got it.

LightNote is not as in-depth as Ableton's course is, but it is much easier for a newbie. There are eight free courses right now, with a few more that you need to pay for.

3. Michael New's YouTube Lessons

Musician Michael New has an innovative style to give free music theory lessons on YouTube. New uses the combination of a MIDI keyboard and a whiteboard to great effect.

He plays notes on the keyboard, and writes what he is explaining on the whiteboard. As the lesson continues, the whiteboard has the information you'll always need in that lesson, perfectly complementing the keyboard it sits above.

As far as visually learning music goes, there's nothing better you will see on the internet.

You should probably start with the Music Theory Fundamentals playlist, but check out the rest of the channel too. There's plenty of great stuff, especially the "How Rhythm Works" playlist.
