How to understand music theory using songs you know

Hear why the songs you love work.

A course in music theory for listeners and players who learned by ear. It covers scales, keys, chords and rhythm as things you can hear, how progressions create tension and release, and why certain songs feel the way they do, using music you already know as the examples.

Type this when Cadence asks what you want to learn

I want to understand music theory well enough to know why songs work. Explain keys, chords, scales and rhythm through music I already know rather than exercises.

Change any word so it fits your situation. The course is built from what you type and a few setup questions.

Three things you can do before the course exists.

Useful on their own. The course is for when you want the whole skill, not just the first move.

  1. Find the home note of a song you love

    Hum along and notice the note the melody keeps settling on. That is the key, and hearing it is the first piece of theory.

  2. Learn the four-chord pattern and spot it everywhere

    One, five, six, four. Dozens of hits share it. Once you know its sound you will hear it on the radio within a day.

  3. Count the beats in a bar out loud

    Most pop is in four. Count along, feel where the snare falls, and rhythm stops being a mystery.

Before the course is built

Setup asks about your situation first.

Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.

  1. Do you play an instrument or sing, or is this for listening?
  2. What music do you know best, so the examples can come from it?
  3. What do you most want to understand: chords, keys, rhythm, or how songs are built?

Right for now

If any of this sounds familiar, start here.

You play by ear and want to know why

Your hands know it and your head does not.

Theory books lose you on page two

Notation, terms, and no music.

You want to write or understand songs

Why this chord after that one, and what makes a chorus lift.

Course arc

Where the course goes, in order.

Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.

01 / 06

Notes and scales

The twelve notes, the major scale, and why it sounds like home.

Keys and the feeling of home

Tonic, tension and resolution.

Building chords

Triads, sevenths, and what colour each adds.

Progressions

The patterns behind a thousand songs.

Rhythm and metre

Beats, bars, groove, and why some rhythms make you move.

Song structure

Verse, chorus, bridge, and why the chorus lifts.

What changes

What you will be able to do, and what you will stop believing.

You will be able to

Hear scales and keys

Major, minor and the feeling of home.

Understand chords

How they are built and why they pull toward each other.

Follow a progression

The handful of chord patterns behind most popular music.

Feel rhythm and structure

Beats, bars, and how a song is put together.

Ideas this course corrects

You need to read music to learn theory

Theory is about sound. Notation is one way to write it down, and it can wait.

Theory kills feel

Theory names what feel already knows. Players who know both have more choices.

Course questions
