16 December 2018:
Today is Beethoven’s 248th birthday.
To celebrate, here’s the soundtrack of a backyard bird singing the first notes of Beethoven’s 5th Symphony. (Song begins at 8 seconds; bird is not visible.)
Here’s an orchestra playing the same four notes.
Beethoven would not have known the song sparrow, whose range is limited to North America, but this song sparrow knows Beethoven.
