Since 175 years the Name GROTRIAN stands for excellence in the art of piano making. The “Compose Exclusif” was released to celebrate the 175th anniversary of the Grotrian company. This specific piano is #17 of the 50 made in total, and was the personal piano of the management. The model has all of the standard Grotrian features such as octagonal strings and “x” style backposts, along with gold plated hardware, birds-eye maple inner cabinet, and a built in hygrometer.
