We yearn to hear the music that we play in tune, in proper pitch, so that the harmonies resonate and sound beautiful together. Your piano wants to be in tune. It’s good for it and good for your ears too!
Just like a car that needs an oil change every so many miles, your piano need a tune up and tuning twice a year too. Without it both your ears and the piano suffer.
Be kind to your piano. Remember to keep it out of direct sunlight, away from the heat and air conditioning ducts. Keep the humidity in the room constant; not too dry, not too damp.
The piano is an exquisite musical instrument, requiring the same care and love that we put into our music and our playing.
