Course Overview

What this course is designed to develop

This course teaches functional vocal harmony using solfege, interval ear-training, and the tuning principles behind real vocal groups from gospel quartets to bands like Fleetwood Mac, CSN, and Boyz II Men. You will learn to identify and sing every interval inside an octave, stack harmony notes by chord tone rather than by guesswork, tune to just intonation against a drone, and write singable 2- and 3-part arrangements. Every lesson pairs a concept with a named drill and a real song so you can measure progress against recordings.

Learning Outcomes

Module 1

Module 1: Hearing and Singing Intervals

Harmony is two notes sounding a fixed distance apart, so the first job is to hear and sing that distance reliably. You build a solfege foundation, learn song anchors for every interval, and train pitch matching against a reference.
