An explanation and PDF is in the following post (354b).

Extended chords are easy to understand -- once you know about the Circle of Thirds.

Essentially, fancy extended chords are built by adding notes incrementally from a key's Circle of Thirds. By including ever more intervals of a third, you can play increasingly more complex harmonies.

Had I only known this in the beginning!

Without the Circle of Thirds, exotic chord names seem mysterious and complicated. WITH the Circle of Thirds, however, everything clicks into place.

🎥 This short video gives you the gist.

Hey! Join Sunday's stream for the first in the Theory Course LIVE series.

We'll be going through the course lessons page-by-page, playing the exercises, etc. -- with questions, answers, and sidebars along the way. It's a new and insightful look into music theory.

Hey, all -- question for you:
Do you have any thoughts on ways to colorize notation?

Folks regularly ask about software to use. And because we have engineers of various types in our community here, I'm hoping some of us may have ideas, or technical know-how.

I think creating an open source tool for community members is an excellent project! It will be very powerful for dissecting and composing songs. With a tool like this, our collective knowledge will rise exponentially.
