“We need music," Nico said. "How's your singing?""Um, no. Can't you just, like, tell it to open? You're the son of Hades and all.""It's not so easy. We need music."I was pretty sure if I tried to sing, all I would cause was an avalanche.”
“Haven’t you heard of the music of the spheres?” asked the dragon. “It’s the music that space makes to itself. All the spirits inside all the stars are singing. I’m a star spirit. I sing too. The music of the spheres is what makes space so peaceful.”
“I promise to sing to you, when all the music dies.”
“I love music, but I can't sing a note.”
“All music is folk music. I ain't never heard a horse sing a song.”
“All the world is made of music. We are all strings on a lyre. We resonate. We sing together.”
