For optimal sound and performance, it’s recommended to have your home piano tuned at least once a year. Pianos that are used more frequently such as churches and school should be tuned every six months. Changes in humidity, temperature, and regular playing can all affect your piano’s tuning stability. Even if your piano isn’t played often, the strings and components still respond to environmental changes over time. Regular tuning not only keeps your instrument sounding its best but also helps preserve its overall condition and value. For new pianos or instruments that have gone a long time without tuning, more frequent adjustments may be needed to bring them back to proper pitch.
