Lucia Dlugoszewski (June 16, 1925 – April 11, 2000) was a Polish-American composer, poet, choreographer, performer, and inventor. She created over a hundred musical instruments, including the timbre piano, a sort of prepared piano in which hammers and keys were replaced with bows and plectra. Dlugoszewski's compositions have been recorded for Nonesuch Records, Folkways, CRI, and other important contemporary music labels. Her 1975 piece Abyss and Caress, for trumpet and small orchestra, was commissioned by the New York Philharmonic and premièred by Pierre Boulez. In 1977, she became the first woman to win the Koussevitzky International Recording Award with Fire Fragile Flight, for 17 instruments – the work became a signature piece for the Philadelphia ensemble Orchestra of Our Time. The recordings for Nonesuch and CRI released in the 70s were reissued by CRI in 2002 as Disparate Stairway Radical Other along with new work for string quartet and timbre piano.
