What to look for: Bright: a high note. Dark: the note slides down and then stops. The little grey disc is feeling the light.
Why it works: The little grey disc is a resistor that light can squeeze. Lots of sun lets the electricity through fast, so the note is high. In the dark the disc squeezes hard, the note goes low, and then it stops.
