Topics by key

This site works differently to most music theory sites.

The theory on how to constuct scales, modes, chords etc is organised by musical key, so rather than explaining the topic in principle, this site gives you the music theory for that topic in the key you are interested in.

If in doubt which key to start from, please use the topic overview links above which will suggest the easiest and most complex keys for each topic.
