The sets were abstract and minimalist, the chorus served the same dramatic purpose as the Greek equivalent (comment and interpretation), and a symphony orchestra provided much of the music. Using such non-traditional measures to achieve a dramatic effect was not common for a Broadway show at the time, so the devices provided a rare outlet for less realistic and naturalistic theatre. Although some reviewers thought the work unclear, several critics are fascinated. Robert Coleman of the Daily Mirror states that "Perfection and great are not words that are to be lightly used...but Allegro is perfection, great." The show ran 315 performances.
