Name given to Stravinsky's Conc. in E♭ for chamber orch. (15 instr.) (comp. 1937–8) because it received its f.p. in May 1938 (cond. by N. Boulanger) at Dumbarton Oaks, the estate in Washington DC of Mr & Mrs R. W. Bliss who commissioned this ‘little concerto in the style of the Brandenburg Concertos’.
