"One Tap of the 'Conductor's Baton'"

I have a whole 'orchestra' inside my head (matter and curiosity), but all the musicians are playing their own notes, creating chaotic noise. Joy's simple explanation was one small tap of the 'conductor's baton'. It wasn't the music. It was just a 'quiet' signal. But from that one small touch, my whole orchestra suddenly fell silent, and then began to play together in orderly harmony. She gave me the tempo.
