Bennett also arranged many fine orchestral suites of Broadway music, which have become staples in the repertoire of Pops orchestras all over the world. Bennett's suites are almost always fine compositions in their own right, with Bennett giving a lot of thought to the melodies and how they should sound in a purely orchestral setting. The suites are more than worth listening to on their own, proving that dramatic music does not always need to be heard in its original context to be effective.
