Pitch Adjustment

The pitch standard for tuning pianos is to tune the A above middle C to a frequency of 440, known as A440.  There are many reasons the overall pitch of the piano can deviate from that standard.  A few of those reasons are:

  • New strings – whether on a new or restrung piano
  • Change in the relative humidity in the piano’s environment
  • Neglecting to have the piano tuned for more than a few years
  • Direct sunlight

When the pitch is more than a certain amount sharp or (most commonly) flat from A440, then two passes through the tuning are required.  The first pass is considered a pitch correction – the purpose of which is to bring all the notes to their proper pitch relative to A440.  The second pass is considered a fine tuning – the purpose of which is to establish all the notes in their proper relationship and to solidify the tuning.

Performing a pitch correction usually necessitates an additional charge to the base tuning fee, since more time and effort are put into the process of restoring your piano to it’s best sound.
