Sound of Harmony is one of the most prized grand pianos ever made in the long and storied history of Steinway & Sons. It was conceived and commissioned by Chinese art collector and music lover, Guo Qingxiang. Sound of Harmony features the inlaid image of Peacock, a traditional ink-wash painting by renowned Chinese artist Shi Qi. Nearly 40 different veneer woods from around the world were used to recreate this masterpiece painting, including Tamo Ash, Tulip Wood, Amboyna Burl, Olive Ash, Rosewood, Macassar Ebony, Birdseye Maple and Brazilian Rosewood.

The Steinway & Sons Concert Grand provides a truly enormous canvas on which the masterpiece was painstakingly depicted using marquetry techniques across the outside and inside of the rim, the outside and inside of the lid, the music desk, the fallboard and on the matching bench. The rim is a work of art in itself, with a total of over 18 feet of veneer. Other features include intricately designed legs and lyre and recessed casters, which give the piano a feeling of permanence in its surroundings. Several elements are made of real gold, including the Steinway & Sons logo and a special medallion with the name of the instrument displayed on the inner rim. This crowning achievement of art case pianos required three full years from inception in 2007 to completion in 2010. This piano was provided for use during World Expo 2010 in Shanghai, which lasted for 184 days and consisted of over 20,000 cultural performances from around the world.
