What is a
Pitch Raise?
If a piano has not been tuned for many years then the pitch will have
dropped further away from where it should be, making it harder for a
tuner to pull the piano back up to the correct tension levels.
Therefore a Pitch Raise* will be required in order for the piano to
sound once again at concert pitch.
To do this, the tension of the strings are increased which puts a huge
strain on the pianos cast iron frame. This is done quickly by raising
the average tension levels above what they should be. It is a rough
tuning that is usually done in 30 minutes. Another tuning is then done
which is known as a fine tune. This is a more accurate tuning which
usually takes an additional hour.
As a Pitch Raise takes more time and effort, the fee for doing it is a
bit more than a standard tuning.
It is recommended that the piano is tuned once again 6-8 weeks after a
Pitch Raise and Fine Tune is carried out. This helps to keep the tension
levels more stable.
Regular tunings (every 6 months is preferable) will avoid the need for a
Pitch Raise in the future.
*A Pitch Raise will only be undertaken after a visual inspection to see
if the piano is structually sound i.e. the strings and frame can handle
the increase in tension.
