About Music Theory Handbook

Music Theory Handbook is an independent explainer site about scales, chords, harmony, rhythm and the other basics of Western music. Each article states established facts plainly and backs them with worked examples, small tables and steps you can check on a keyboard or a staff.

Accuracy comes first. The articles follow standard music theory teaching, and any error that is found gets corrected on the page. Corrections are welcome, so if you spot a wrong note name, interval size or claim, please report it.
