WHAT COMPOSER was threatened with arrest in Boston in 1944 for using a dominant seventh chord in his arrangement of the "Star-Spangled Banner"? The police subsequently conceded that the law only prohibited arranging the anthem "as dance music, as an exit march, or as a part of a medley of any kind", though given the composer’s famous history with the Ballets Russes perhaps a fear that the arrangement would qualify as dance music would not have been entirely misplaced.
