So you want to know more about tuning...


Included below is everything and possibly more than you could ever want to know about the process of aural piano tuning.


What do we listen to?

Sure, knowing the process is great, but what are we tuning to in each step? This is where knowing the partial sequences are critical.

Coincident Partials:

When you play multiple note together their partials begin to vibrate together. The more notes you play the more partials. In tuning intervals we are listening to two notes and the partial they have in common, we call this a coincident partial. We will use the interval from the temperament sequence. This is step 3(part 1), we are tuning F on key #33 (F33) to A on key #37 (A37)

The partials of F are: F, F, C, F, A, C

The partials of A are: A, A, E, A, C#, E



How should the intervals sound? Over the centuries cultures have appreciated different sounding intervals than we use today. Today we tune pianos with an "Equal" temperament, that is we tune so the notes are equidistant from each other.

The following are how specific intervals should be set:

In the temperament area the goal is to have all 4th & 5th intervals nearly perfect, with 3rds & 6ths progressively getting faster as you move up the scale. There are many other intervals that can be used but to begin this is sufficient.
