“ | The Nine Muses cranked up the tunes, and I realized the music was whatever you wanted it to be: the gods could listen to classical and the younger demigods heard hip hop or whatever, and it was all on the same sound track. No arguments. No fights to change the radio station. Just requests to crank it up. | ” |
–Percy Jackson listening to the Muses, in The Titan's Curse. |
Calliope, Clio, Erato, Euterpe, Melpomene, Polymnia, Terpsichore, Thalia and Ourania are the Muses, nine goddesses who preside over inspiration, the sciences, the arts, poetry and literature. Their leader is the god Apollo, who lead them in song.
History
Early life
According to Hesiod's Theogony, the Muses were born in the region of Pieria, wherein lies Mount Olympus. They were conceived when Zeus appeared before Mnemosyne and lay with her for nine consecutive nights.
Some time later, Thamyris challenged the Muses to a singing contest. They won and punished Thamyris by blinding him and robbing him of his singing ability. The center of their cult was Mount Helicon, located in Boeotia.
Attendants of Apollo
In one myth, the Muses judged a contest between Apollo and the satyr Marsyas. After they declared Apollo the winner, the god flayed Marsyas alive as punishment.
Tale of Orpheus
The Muses gathered the pieces of the dead body of Orpheus, son of Calliope, and buried them after he was mutilated by the Maenads on Dionysus' orders.
Punishing the Nine Sisters
Pierus, king of Macedonia, named nine of his daughters after the Muses. They claimed that their skill was a match for the goddesses, and challenged them to a contest. Nymphs were elected to judge the contest, and the Muses defeated the princesses, who were turned into birds for their insolence.
Percy Jackson and the Olympians
The Lightning Thief
The Muses were shown to be starting a concert on Olympus when Percy returns the Master Bolt. The Muses and everyone else bow to Percy as a sign of respect for performing a great task for the gods. As the gods celebrate, the Muses play music that sounds like anything you want, so no one argues about the music.
The Titan's Curse
The Muses perform at the final celebration after the gods had decided that Percy Jackson and Thalia Grace were not going to be killed. According to Percy, everybody hears the music they only want to hear, like classical for the gods and hip hop for the younger demigods. He later shares a dance with Annabeth Chase and the song he hears changes to a slow one, though he was not sure what she was hearing.
The Last Olympian
A few Muses are shown playing some tunes on Olympus, but their hearts were not into it because of Kronos' attack on Olympus while the gods were out fighting Typhon.
