When they first started out making pianos, the instruments could only play in one key. Eventually they figured out how to make everything slightly but equally out of tune, so that you now had a 12 tone piano that could play in all keys.

This concept is called "Equal Temperament" tuning, and it's what your ears are used to music from the Western part of the world. The scientifically exact tuning is called "just" tuning, and in this lesson I'm going to use a tone generator to show you the difference, and after this we'll talk about how it applies to guitar tuning.
