Sharpen your ear fast with this free music theory course—learn scales, intervals and chords in 1 hour and earn a certificate to boost your singing skills.

In this free course, learn about

  • Core music theory basics: notes, scales, intervals, chords, and how they function in songs
  • When to spell notes with sharps vs flats and how enharmonic choices affect readability and theory
  • Differences between natural minor and harmonic minor scales and how each changes harmony
  • Naming altered intervals like C–E double-flat and recognizing diminished/compound alterations
  • How to build diatonic triads from a major scale using stacked 3rds (I, ii, iii, IV, V, vi, vii°)
  • The role of the tritone in diminished chords and its tension/resolution in other chord types
  • Interval inversion rules, especially how perfect intervals invert to perfect intervals
  • Borrowing a tritone (via secondary dominants/mixture) to increase pull toward the V chord in C major

Course Description

Build confidence in your singing by understanding the logic behind the notes you already use. This free online course delivers a clear, one-hour dive into music theory that helps you hear pitch relationships, recognize tension and release, and make smarter choices when you sing melodies or harmonies. Instead of feeling like theory is a separate subject, you will connect it directly to musical intuition: why certain notes sound stable, why others crave resolution, and how patterns repeat across keys.

You will get comfortable with the musical alphabet and the real-world reasons musicians choose sharps or flats, so reading and talking about notes becomes simpler and more consistent. From there, the course clarifies how minor sounds are built by comparing natural and harmonic minor, giving you a practical way to predict the color a melody will create. You will also sharpen your understanding of intervals, including what changes and what stays the same when intervals invert, which is a powerful shortcut for both ear training and sight-singing.

Chords stop being mysterious when you can see how they grow out of a major scale. You will learn to recognize the repeating structure that produces familiar triads and seventh chords, and you will understand why certain chord tones create momentum. A key highlight is the tritone: you will explore its role inside diminished chords and how it functions in other harmonic settings, revealing how composers and songwriters create pull toward the dominant and drive progressions forward. This insight makes it easier to anticipate where a song is going and to sing with stronger phrasing and intention.

With quick checks for understanding and focused questions that reinforce each concept, you can test yourself as you go and consolidate what you learn. By the end, you will have a more reliable mental map of scales, intervals, and harmony—skills that support better tuning, faster learning of songs, and clearer communication with other musicians. Complete the course to strengthen your musical foundation in a single sitting and walk away with a certificate that fits neatly into your learning journey.
