The piano requires various forms of maintenance to produce its best sound. Maintenance is also important for the appearance of the piano. Pianos that are prized by their owners are tuned regularly, usually once every six months for domestic pianos, and always just before a performance in concert halls. The longer a piano is left out of tune, the more time and effort it will take for a technician to restore it to correct pitch. When a piano is only slightly out of tune, it loses the glowing tonal quality characteristic of a freshly tuned piano, probably because strings slightly out of tune with one another have weaker sympathetic vibrations. Pianos that are more than slightly out of tune tend to be unpleasant to play and listen to, to an extent that varies with the ear of the listener. A tuning hammer is the main tool that piano technicians use. Pianos go out of tune primarily because of changes in humidity. Tuning can be made more stable by installing special equipment to regulate humidity, inside or underneath the piano.
