In which city was the Symphony for Classical Orchestra in B-flat major completed by Harold Shapero who undoubtedly derived a fair amount from the American composer, teacher and writer known as the 'Dean of American Composers'?
Massachusetts
Symphony for Classical Orchestra (Shapero)
Harold Shapero completed the Symphony for Classical Orchestra in B-flat major on March 10, 1947, in Newton Centre, Massachusetts.
 It is written for an orchestra consisting of piccolo, 2 flutes, 2 oboes, 2 clarinets in B-flat, 2 bassoons, contrabassoon, 2 horns in F, 2 trumpets in C, 2 tenor trombones and one bass (silent until the Finale), timpani and strings.
 Although labelled "Classical," many of the work's features point to Beethoven rather than Haydn or Mozart, such as "the way in which Shapero paces himself, alternating long passages in the tonic and the dominant, with fast, dramatic modulations often reserved for transitions and developments."
 Nicolas Slonimsky remarked on how the piece is "premeditatedly cast in the proclamatory key of B-flat major, the natural tonality of the bugle, and ending in a display of tonic major triads."
 But there are modern features as well, with "the work's orchestration, in general, ... distinctively bright and brassy, and undoubtedly derived a fair amount from Piston and Copland, as well as from the composer's experience as a dance band arranger."
Aaron Copland
Aaron Copland ( ; November 14, 1900December 2, 1990) was an American composer, composition teacher, writer, and later a conductor of his own and other American music.
 Copland was referred to by his peers and critics as "the Dean of American Composers."
 The open, slowly changing harmonies in much of his music are typical of what many people consider to be the sound of American music, evoking the vast American landscape and pioneer spirit.
 He is best known for the works he wrote in the 1930s and 1940s in a deliberately accessible style often referred to as "populist" and which the composer labeled his "vernacular" style.
 Works in this vein include the ballets "Appalachian Spring", "Billy the Kid" and "Rodeo", his "Fanfare for the Common Man" and Third Symphony.
 In addition to his ballets and orchestral works, he produced music in many other genres including chamber music, vocal works, opera and film scores.
