A piano is tuned by adjusting the tension of the strings so that the harmonics are properly lined up.

A piano less than two years old should be tuned 3-4 times a year depending on the humidity control. A piano older than 2 years old should be tuned 2-4 times a year depending on the humidity control.

In order for the sound on a piano the to be uniform all of the parts must move efficiently from one key to the next. Regulation is the adjustment of the action parts to allow for uniform movement from key to key. Regulation should be preformed approximately every 5 years but can vary based on the amount of play. If your piano is played on a regular basis you may find the need to have the regulation worked on more frequently. Voicing is often performed at the same time as the regulation.
