Most Americans know the words to “The Star-Spangled Banner.” Few know the tune wasn’t written for America at all.The melody Francis Scott Key used was the popular English tune "To Anacreon in Heaven," originally the constitutional song of the Anacreontic Society, a gentlemen’s music club in London.The next time you bail on the high note at a ball game or a July 4 cookout, don’t blame your lungs.The club met regularly for a formal concert, dinner, and social time during which members entertained each other with songs. Its 1780 membership included peers, commoners, aldermen, gentlemen, actors, and tradesmen.Although it is often described as a “drinking song,” the song was not a barroom ballad — it was convivial, but in a special and stately way. The verses were sung by a solo singer, with the entire society joining in only on the refrain.When Key wrote his lyrics on September 14, 1814, after watching the British attack Fort McHenry during the War of 1812, he wasn’t composing original music — he was setting new words to a tune Americans would have instantly recognized.RELATED: Whitlock blasts Victor Wembanyama for flagrantly disrespecting national anthem in NBA finals Nik Pennington/MLB Photos/Getty ImagesHe wasn’t the first American to do it. By 1798, many new songs had already been set to the melody, including “Adams and Liberty,” a patriotic song in praise of the nation’s second president. By 1820, 84 sets of lyrics had been written to it in the United States alone.The tune’s origins also explain a common modern complaint: The anthem is famously difficult to sing. It was intended for solo performance by an experienced vocalist — never designed for mass singing.The composer’s identity was itself a mystery for generations. John Stafford Smith was identified as the writer of the original tune only in the 1970s, when a librarian in the music division of the Library of Congress tracked him down.So the next time you bail on the high note at a ball game or a July 4 cookout, don’t blame your lungs. Blame an 18th-century London music club that never expected anyone outside its dining room to try.Like Blaze News?
