Restore a Piano Not Tuned for Years

In Singapore, many household pianos sit unused for three, five, or even ten years without tuning. When reactivating such a piano, a standard tuning cannot be performed directly, as it may easily cause string breakage or pinblock damage. The correct process involves three steps.

Step one is assessing the piano‘s condition. Remove the top and lower door panels to check for severely rusted strings, obvious cracks in the soundboard, or hammers damaged by insects or excessive wear. If these issues exist, repairs are needed before pitch restoration.

Step two is a pitch raise. The tuner raises the average tension of all strings close to standard pitch, but not all the way in one pass. This process typically takes one to two hours and may need to be done in two sessions, with several days in between to allow strings to adapt to the new tension.

Step three is a fine tuning. One to two weeks after the pitch raise, once the piano‘s tension has stabilized, a complete fine tuning is performed, adjusting all notes precisely to the 440 Hz standard.

Be aware that even after pitch restoration, a long-untuned piano will still have poor stability. Three to four tunings in the first year after restoration are recommended to help strings and the pinblock gradually adapt to a stable state. If multiple strings break or tuning pins become severely loose, partial part replacement or even replacing the piano may be necessary. Regular maintenance is always more economical and reliable than a one-time major restoration.
