Tuning
Piano Tuning is the act of making adjustments to the tensions of the strings of a 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 interaction between notes, which is different for every piano.
Pianos are usually tuned to a modified version of the system called equal temperament. In all systems of tuning, every pitch may be derived from its relationship to a chosen fixed pitch, which is usually A440.
Piano Tuning requires patience, a good ear and practice. The piano is a complex instrument, requiring all work – tuning, repairs, cleaning, etc. to be done by an experienced, caring professional piano tuner. Keep in mind that professional piano tuners spend years learning the nuances, craft and art of Piano Tuning.
Most piano manufacturers recommend that pianos be tuned a minimum of every 6 months.
