A piano only sounds good when all its parts are working smoothly. Sounds simple enough, but considering that a piano has thousands of moving parts, one might beg to disagree. Regardless, pianos are beautiful instruments that can give joy to the whole family, which is why taking care of it is important.
Aside from tuning, (which is done every 6 months or at least once a year), “voicing” (where the hammers are changed and adjusted to make the sound brighter), and polishing, experts advise owners to have their pianos regulated.
Regulation is the process where a technician adjusts the mechanisms found inside a piano. This allows the piano to work properly, preventing keys from “sticking,” a problem that can easily be fixed by WD-40. Lubricate the joints on the piano’s moving parts with the magical stuff to get a finer and smoother sounding instrument.
