The industry standard for ongoing tuning is to have your piano tuned at least once per year, regardless whether it has had regular playing or the bare minimum of playing.
The piano is under considerable tension at rest with both the piano strings and the soundboard being sensitive to changes in the weather seasons, humidity or dry heat, these changes are continually changing even without the piano being played.
The actual playing of the piano also causes the piano to move out of tune, as the hard felt hammers strike each note, time after time.
Many pianos require tuning more frequently than the minimum, for example Music Teachers’ pianos require tuning at least six monthly and schools once a school term to ensure that the instruments are kept in tune and well maintained.
Similarly venues such as Churches, Reception Venues, Theatres and Public Halls where the instruments are subjected to the extremes of temperature and humidity due to both airconditioning and “Body Heat” derived from the audiences and patrons, therefore the Piano Tuner must advise the venue of the most efficient approach and frequency for the ongoing maintenance and piano tunings.
