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.At Chicago Piano Restoration We Specialize in Piano Tuning, Minor & Major Piano Repairs, Restoration, and Complete Rebuilding, We tune and Service Pianos in the Following Cities, Chicago IL, Downtown Chicago, Oak Park IL, Elmhurst IL, River Forest IL, Forest Park IL, Elmwood Park IL, Riverside IL, Franklin Park IL, Park Ridge IL, Glenview IL, Niles, Winnetka IL, Lake Zurich IL, Arlington Heights IL, Wilmette IL, Skokie IL, Palatine IL, Northbrook IL, Highland Park IL, Evanston IL, Lombard IL, Bensenville IL, Rosemont IL, Downers Grove IL, Westmont IL, Darien IL, Burr Ridge IL, Brookfield IL, LaGrange IL, Westchester IL, Western Springs IL, Willow Springs IL, Willowbrook IL, Oak Brook IL, St. Charles IL, Wheaton IL, Geneva IL, Winfield IL, Clarendon Hills IL, Oak lawn IL, Palos Hills IL, Palos Hight IL, Aurora IL, Joliet IL, Berwyn IL, Bloomingdale IL, West Chicago IL, Carol Stream IL, Naperville IL, Near Me, Piano Tuner Chicago.
