In honor of the two hundredth anniversary of the national anthem, choristers are converging on the National Mall to stage the largest sing-along ever of “The Star Spangled Banner.” The National Museum of American History, which is sponsoring the event, is encouraging would-be warblers to join Anthem for America parties across the country. If there isn’t a party near you, just tune in and sing along with the huge chorus at 4 o’clock today.

What an anthem we have! One of the most difficult to sing of any, with a wide-ranging melody and a high note at the end. A strange sort of anthem for a democracy, when you think about it. “My Country ‘Tis of Thee” is easier, though undeniably British. Or even “America the Beautiful,” though it has its share of high notes, too.

Also interesting, I ponder today on Flag Day, is the fact that our anthem asks questions rather than makes statements. And it’s written in second person. “Oh say, can you see?” These features make it more conversational than most. It’s a song that wonders more than it pronounces, that marvels more than it prescribes. And in those ways, it is endearing.
