Just a reminder, as spring has arrived and with the warmer weather comes higher humidity levels. Recently, preparing a piano for the upcoming choral concert at McKeesport High School we registered the humidity level at a reading of 64.3%. Ideal temperatures for optimal piano care is 68-72 degrees. Recommended humidity levels 45-50%. The more the environment changes from the ideal temperature and humidity recommendations where the piano is housed; the more fluctuations one can expect with their piano. Pianos will tend to go sharp in the summer months and flat during winter months. This is the reason all major piano manufacturers recommend tuning at least twice a year.
