Music Theory for complete beginners (in 29 Minutes)

Most theory lessons start with rules and names. This one starts with sound: every idea is played on piano before it gets a name. In 29 minutes it covers the core of music theory in nine levels, from notes, rhythm and scales through intervals, chords, chords in a key, tension and release, and the circle of fifths, to melody. Along the way one original song grows level by level, from a single C to a full I-V-vi-IV arrangement.

If you are new to theory, it gives you a map of how the pieces fit together. If you have played or taught for years, use it as an ear check. Ten tests run through the lesson, from telling major from minor to a final test on a four-chord progression in D. Keep score and see how many you get on the first listen.

Anything that took more than one listen is worth training. ToneGym has games for the skills in this video, from Scale Spy for scales to Melody Hunter for melody, with levels that go far beyond what the lesson covers. It's free to start: tonegym.co.
