The Sing for Hope Pianos project is one of New York City's largest public art projects. It brings 88 (one-per-key) artist-painted pianos for three weeks in June each year since 2011 (hundreds, over the years) to parks, street corners, subways, and other outdoor public spaces of the five
boroughs of New York City. The pianos are available for anyone to play, for free. In 2010, artist
Sophie Matisse, the great-granddaughter of French painter
Henri Matisse, hand-painted four
Kimball pianos that had been donated for the cause, including painting the piano keys. In 2011, fashion designers
Isaac Mizrahi,
Diane von Furstenberg, and
Kate Spade painted pianos for the project, and the following year fashion designer
John Varvatos painted a piano silver. Following their three-week public residency, the Sing for Hope Pianos are donated to schools, hospitals, healthcare facilities, and community centers. ==List of artist partners==
