The Fundamentals of Harmony · a course by Andrew Sheron

Stop memorizing rules.
Start understanding sound.

Most music theory is a history lesson in disguise. This isn't. Starting from a single vibrating string, we derive the deep language of musical harmony.

Problem

Rote memorization, not knowledge

Most music courses force students to learn naming conventions invented by people and religious institutions centuries ago.

Many musicians end up stuck; fluent enough to use the words, but never shown any explanation as to where the words come from.

The approach

Physics, logic and mathematics.
Not human invention.

This course strips away the baggage and works from the objective, physical underpinnings of sound. We interact with playable digital canvases to discover how frequency, the harmonic series and musical intervals emerge on their own, and watch a vibrating string divide itself into octaves and fifths without anyone telling it to.

Nothing is asserted. Everything is derived, from the ground up.

What you get

Four things.

01

Interactive digital learning

Leave textbooks behind. Harmony learned intuitively through sleek, playable visualizations, in a browser, on any device.

02

The objective truth of sound

Understand harmony from the ground up, and see how it emerges in nature rather than from a rulebook.

03

Lifetime access, future updates

Pay once. As the course expands with new lessons, interactive features and materials, you get every update at no extra cost.

04

The Color Tree poster

A high-resolution digital download of the poster, included with the course. Looks great as a lock screen.

Lesson 1 · free, right now

Start with a click.

One click a second. Speed up the clicks and around twenty per second they stop sounding like rhythm and become pitch.

Then a string. Pluck it and find the other notes hiding inside it. By the end of Lesson 1, harmony has emerged from zero assertions.

Runs in the browser, makes sound. Nothing to install, no instrument required - though it helps to have one nearby.

Start Lesson 1

About twenty minutes. Sound on, or headphones.

Questions

Do I need to know how to read music?

No. There is no notation anywhere in this course.

How much do I need to know already?

Nothing. Lesson 1 starts at "what is a sound." If you already know your theory, the later lessons will still be new to you.

How long is it?

Twenty minutes to an hour a lesson, depending how much you play with the demos. Playing with the demos is the point.

Will it work on my phone?

Yes. Every lesson works in portrait and landscape, and makes sound either way.

Is it self-paced?

Yes. No cohort, no schedule, no expiry.

How does this relate to your apps?

The apps are tools; this is the argument behind them. The apps.
