2112 Discovery

What can this strange device be?
When I touch it, it gives forth a sound
It’s got wires that vibrate and give music
What can this thing be that I found?
See how it sings like a sad heart
And joyously screams out its pain
Sounds that build high like a mountain
Or notes that fall gently like rain
I can’t wait to share this new wonder
The people will all see its light
Let them all make their own music
The priests praise my name on this night
