The Star Spangled Banner spans 1.5 octaves.
That’s more range than most singers can reach comfortably.
The trickiest part is that it starts about two notes from its bottom. Most songs start around the middle of their range. If you try that with the Star Spangled Banner you’ll hurt yourself when you try to get up to the “rockets red glare”.
I can sing it comfortably. But not exactly professionally, though our high school chorus won best in state. If I sang all day and took lessons, I’d be passably good. My cat would probably bite me though.
Yes.
Good, vocally trained singers can do it.
(Operatic singer range is at least 2 octaves!)
Jessye should be able to do it!
But we, the ordinary folks, have hard time to do it without botching it.
That why we usually do not sing it.
Star Spangled Banner is usually sung just by some leading singer only.
And even they botch is sometimes.
I sing it, proud. Who cares about those covering their ears - they’re not listening anyway!
