Here's an update:  A video of this song was made on December 8,
2017, in Stephanie Bailey's Physics 6A class. This was the last
class meeting of the Fall Quarter.  The videographer was Alice
Durand.

The resulting video is now posted on YouTube, at
https://youtu.be/vtWPXRTQQ7Q
A click on the video line should lead you to it.

The gravity.mp3 file is rudimentary, just made from a MIDI file
produced from the score in gravity_2017.pdf.  We look forward to
making, at some point, a better sound file.

Meanwhile, just enjoy singing the song.
