It has been around for a few years, but if there is one book we'd recommend reading it is Music Theory for Computer Musicians. It’s a great book that tells you everything you always wanted to know about Music Theory.

There’s something in this book for everyone. From the characteristics and properties of sound to topics like notes, scales, chords, rythm, tempo and note lengths, melodies and motives, the author dedicates plenty of pages to explain every aspect in a concise and clear way.
