Piano tuning is the act of making minute adjustments to the tensions of the strings of an acoustic piano to properly align the intervals between their tones so that the instrument is in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the vibration interaction among notes, which is different for every piano, thus in practice requiring slightly different pitches from any theoretical standard. Pianos are usually tuned to a modified version of the system called equal temperament (see: Piano key frequencies, for the theoretical piano tuning).
In all systems of tuning, every pitch may be derived from its relationship to a chosen fixed pitch, which is usually A440, above middle C (pitch 261.626 hertz). However, others prefer to use A444 when tuning in the key of C. Some electric pianos or electronic keyboards might be set in the key of B-flat, to use the same sheet music as common musical instruments.
Piano tuning is done by a wide range of independent piano technicians, piano rebuilders, piano-store technical personnel, and hobbyists. Professional training and certification is available from organizations or guilds, such as the Piano Technicians Guild. Many piano manufacturers recommend that pianos be tuned twice a year.
