A composer’s work can grow in influence far beyond what it enjoyed during a composer’s lifetime. Water Music, by George Frideric Handel, probably wasn’t an 18th-century blockbuster. “It would have been regarded at the time as kind of a relatively minor, obscure work by Handel. Nothing like it is today, where it’s one of Handel’s big hits,” said Temple Music History Professor Steven Zohn, an expert on Baroque music.
