Tuning
Piano tuning by ear is an art best passed on from person to person, one on one. This knowledge of the art I was privileged to receive from my dad, which he received from his father, dating back to 1932. Tuning by ear-or aural tuning as it's called, is generally preferred.
It is recommended by piano manufacturers to have your piano tuned every 6 months, some can go longer, at least once a year. Moving across town or across the state will cause pianos to go out of tune. Pianos can be moved and tuned at the same time, within the same climate. If a pianos environment changes dramatically, relating to humidity or temperatures, or altitude, a time to acclimate is necessary.
Pianos are manufactured to be tuned to A-440, which is 440 cycles per second or 440 hertz, the universal standard. All the music you hear will adhere to this standard pitch. If you are told by your piano tuner that you need a pitch raise, it means the pitch is below A-440, to far to be stretched up in one tuning. He may want to do two tunings in a row or divide it into two trips, it would depend on how flat it is.
Sometimes a piano can't be tuned until repairs are made. Some of the repairs might include bass or treble bridge repair, sound board repair, string or loose tuning pin replacement.
The best way to insure that you and your family gets the most enjoyment from your piano, is to keep it sounding and playing the best it can. I appreciate the quietest environment that you can provide, as this enables me to give the best service possible.
