“The Star-Spangled Banner ” is the national anthem of the United States of America. The lyrics come from “Defence of Fort M’Henry”, a poem written in 1814 by the 35-year-old lawyer and amateur poet, Francis Scott Key, after witnessing the bombardment of Fort McHenry by British ships of the Royal Navy in Chesapeake Bay during the Battle of Fort McHenry in the War of 1812.The poem was set to the tune of a popular British song written by John Stafford Smith for the Anacreontic Society, a men’s social club in London. “The Anacreontic Song” (or ” To Anacreon in Heaven “), with various lyrics, was already popular in the United States. Set to Key’s poem and renamed “The Star-Spangled Banner”, it would soon become a well-known American patriotic song. With a range of one and a half octaves, it is known for being difficult to sing. Although the poem has four stanzas, only the first is commonly sung today.The Star-Spangled Banner” was recognized for official use by the Navy in 1889, and by President Woodrow Wilson in 1916, and was made the national anthem by a congressional resolution on March 3, 1931 (46 Stat. 1508, codified at 36 U.S.C.
