|What’s A Pitch Raise?
What happens when you don’t tune your piano for a long time: the pitch drops further and further away from where it should be, and it becomes harder for a piano tuner to tune. Pianos generally go out of tune during our long winter months, and don’t come back up to where they previously were.
Tuners have to raise the tension of over 200 strings, which puts a lot of strain on the piano’s structure. It’s impossible to make such a big jump in pitch and have a stable tuning in one pass. So what they have to do is first raise all the strings to their proper average tension levels, and only then can the piano be accurately tuned. This is called a “pitch raise”.
A pitch raise/lowering requires more time and effort than a regular tuning, and as a result, a piano technician’s fee is a bit higher.
Regular tunings – at least once a year (every 6 months is preferable and recommended) will prevent the need for a pitch adjustment in the future. Like many other things, pianos require regular preventive maintenance.
