Course Overview

What this course is designed to develop

Most musicians can play but cannot explain why a chord change pulls the way it does, how to transpose a song into a singable key, or what name to give the notes under their fingers. This course fixes that by building theory from the ground up: you start with the staff, the 12 pitches, and the formula for every interval, then construct major and minor scales, the circle of fifths, triads and seventh chords, and the functional roles (tonic, subdominant, dominant) that drive progressions in pop, jazz, classical, and film. You also master rhythm and meter and build a daily ear-training habit using named tools, so theory becomes something you can hear and use, not just diagram.

Learning Outcomes

What the learner should be able to understand, build, or execute.

01

Read pitch and rhythm in treble and bass clef, including key signatures and accidentals

02

Construct any interval, scale, and key signature using semitone formulas and the circle of fifths

03

Build and identify major, minor, diminished, and augmented triads and seventh chords

04

Analyze chord progressions by Roman numeral and explain tonic, subdominant, and dominant function

05

Notate and count rhythm accurately in simple and compound meters

06

Train your ear to recognize intervals, chord qualities, and progressions using a daily practice routine

Module 1

Module 1: Reading Music: Notation, Pitch, and the 12 Notes

Music notation is a precise map of pitch and time. This module teaches you to read the staff in both common clefs, name every pitch including sharps and flats, and understand the 12-note chromatic system that everything else is built on.

Module 2

Module 2: Intervals, Scales, and Keys

Intervals are the raw material of all melody and harmony. This module teaches you to measure any interval, build major and minor scales from their step patterns, and navigate all keys using the circle of fifths.

Module 3

Module 3: Chords and Functional Harmony

Harmony is how notes sound together and move over time. This module builds triads and seventh chords from intervals, assigns Roman numerals, and explains the tonic, subdominant, and dominant functions that drive real progressions.
