Harmony is Key!

Have you ever wondered, why certain songs just don't match, even though their beats perfectly align?

Often this is the case, because they are in a different tonal key. Songs in incompatible keys simply sound dissonant when mixed together.

To mix your songs harmonically, you first have to figure out, what key they are in. And if you're a good musician, you might be able to do so, by listening and playing chords on your piano. Most likely though, you are much better off letting beaTunes determine the keys of your songs automatically with its kick-ass, state of the art key detector.

Once you have determined the key of songs in your library, you can build playlists based on them (and other properties). The Open Key Notation will help you to find matching songs, even if you're not a professional musician.
