Piano tuning

In each note, the strings in a piano are tuned in unison. If you're going to
tune an entire piano yourself, you should keep in mind that if you tune the
notes using a chromatic tuner or something like that, the piano will sound
somewhat out-of-tune, because it won't be tempered right. If there's a
single string that's giving you trouble, fine, but there are a couple odd
things about tuning a piano that you should take in to account.

The math of it is explained pretty well here:

In my experience, a professional piano tuner uses a tuning fork to get a
center reference note, and tunes the rest of the keys by ear. This is, to
say the least, a little tricky.

One last note: a drum key fits the tuning pegs of 99.9% of all pianos. It's
a little harder to turn than a normal piano tuning key (especially on the
lower strings) but it will work in a pinch.
