Welcome to the GCDYO 's music theory webpages!
This new section of the site demonstrates and tests aspects of music theory: the kind of music skills tested in Associated Board exams. The theory of music includes things like keys and clefs, performance directions, understanding of chord progressions and harmonies, time signatures and ornamentation.
You won't find any lessons or help with learning theory here, but you can test what you already know.
All the pages in this section are interactive, and some are still experimental, so if you find an error or have any other comments, we would like to know. Please contact us through the feedback page.
