Star-Spangled Banner (flag) in the context of "Battle of Baltimore"

"The Star-Spangled Banner" is the national anthem of the United States. The lyrics come from the "Defence of Fort M'Henry", a poem written by American lawyer Francis Scott Key on September 14, 1814, after he witnessed the bombardment of Fort McHenry by the British Royal Navy during the Battle of Baltimore in the War of 1812. Key was inspired by the large U.S. flag, with 15 stars and 15 stripes, known as the Star-Spangled Banner, flying triumphantly above the fort after the battle.

The poem was set to the music of a popular British song written by John Stafford Smith for the Anacreontic Society, a social club in London. Smith's song, "To Anacreon in Heaven" (or "The Anacreontic Song"), with various lyrics, was already popular in the United States. This setting, renamed "The Star-Spangled Banner", soon became a popular patriotic song. With a range of 19 semitones, it is known for being very difficult to sing, in part because the melody sung today is the soprano part. Although the poem has four stanzas, typically only the first is performed with the other three being rarely sung.
