Tuning is the first point for many pianos and the most often needed service.
Why does my piano need a Tuning and/or a Pitch Raise?
Time – The string doesn’t like to be under tension, and will work to get to a neutral state.
Environment– The piano expands and contracts with room changes, this drives it out of tune faster.
How often should my piano be Tuned?
Play – Frequency of use puts the piano out of tune quicker.
