Provides Regular Care for Your Piano:
Tuning
The approximate 220 strings on your piano exert about 40000 pounds of tension on the plate and frame, and about 600 pounds of downbearing on the bridges and soundboard. Seasonal changes in the humidity, as well as the normal, continual decrease of static tension, cause all pianos to go out of tune.
Depending on where you live, the amount of humidity change from season to season, the quality and condition of your piano and how much the piano is played, your piano could need tuning two to four times yearly.
During each service call Plum will check and tighten the pinblock bolts (and rim bolts in grands), check and adjust the pedals, check and tighten the bench bolts, and inspect your piano for repairs and adjustments that might be needed or recommended
