The Boys from Syracuse is a musical with music by Richard Rodgers and lyrics by Lorenz Hart, based on William Shakespeare's play The Comedy of Errors, as adapted by librettist George Abbott. The score includes swing and other contemporary rhythms of the 1930s. The show was the first musical based on a Shakespeare play. The Comedy of Errors was itself loosely based on a Roman play, The Menaechmi, or the Twin Brothers, by Plautus.
