Density 2036 is a 24-year project begun by Claire Chase in 2013 to commission a new body of repertory for solo flute each year until the 100th anniversary of Edgard Varèse’s groundbreaking 1936 flute solo, Density 21.5. Chase will commission and premiere a new program of flute music every year until 2036. Each piece in the project will expand the boundaries of the instrument. For the ten-year anniversary of Density 2036 from May 18-25th, 2023, Chase performed all Density commissions up to the present in a series of concerts at Carnegie’s Zankel Hall and in free performances at The Kitchen’s Westbeth Loft as part of Carnegie Hall Citywide.  Central to the Density 2036 project is a commitment to supporting an international, multigenerational community of flutists who will take the Density repertoire in new interpretive and performative directions. The Density Seeds program makes possible the performance of miniature works adapted from the Density catalog that are playable by flutists of all ages; the “seeds” are freely downloadable on the density2036.org website. The Density Fellows program, launched this year in celebration of the 10th anniversary of the project, will provide ten exceptional emerging flutists with the resources to intensively study Density repertoire of their choosing. Fellows will receive mentorship from Claire Chase and the Density composers, as well as support for their own performances and recordings. The Density Roots initiative is an open, community-controlled interactive map that will archive performances of Density repertoire by flutists worldwide over the 24-year span of the project. Density 2036 is supported by The Pnea Foundation, a 501(c)(3) organization whose mission is to advance the flute and its repertoire in the 21st century.
