tuning_iconTuning means correcting the pitch of every note by tightening the strings. Each piano string is initially stretched to a tension of approximately 90 kg, but with time loses some of the tension and thus pitch.
(Just out of interest, the strings of a piano exert a total force of between 15 000kg and 20 000kg on the cast iron frame!)


  A piano needs to be tuned at least once a year, and sometimes more often. Tuning takes anything from one to three hours, depending on the frequency of previous tunings.
  If a piano has not been tuned for a long period it will lose its pitch and will need one or more pitch raises, and a final tune to bring it back into line.

Regulation is the adjustment the various parts of the action (the inside mechanism) so that the touch, strike motion and release all function at their optimum. Any single note consists of approximately 36 moving parts!

Tuning and regulation are thus best left to the experts.
