Orchestra

Every live production of Cats is accompanied by an orchestra, which may vary in size and instrumental makeup. One unique aspect of Cats is that the orchestra is hidden from the audience in a sound booth backstage. For more information, see The Sets/Junkyard.

The original orchestrations were arranged by David Cullen and Andrew Lloyd Webber. The 16-piece licensed version is considered the official "definitive" version. Touring productions typically travel with a small core orchestra, using local musicians at each tour stop to provide additional instrumentations.
