Muses

"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

The Muses were the daughters of Zeus and Mnemosyne. They inspired and presided over several creative arts. Muse usually means inspiration, either for an artist or poets, and people would pray to the muses for inspiration.



History
The Muses judged the contest between Apollo and Marsyas. They also gathered the pieces of the dead body of Orpheus, son of Calliope, and buried him. They blinded Thamyris for his hubris in challenging them to a contest.

The Muses are also the companions of the god Apollo.

There are nine Muses:
 * Calliope, Muse of Epic Poetry
 * Clio, Muse of History
 * Erato, Muse of Love Poetry
 * Euterpe, Muse of Music
 * Melpomene, Muse of Tragedy
 * Polyhymnia, Muse of Sacred Poetry
 * Terpsichore, Muse of Dance and Epic Poetry
 * Thalia, Muse of Comedy, Namesake of Thalia Grace
 * Urania, Muse of Astronomy

The Titan's Curse
The Muses perform at the final celebration after the gods had decided that Percy and Thalia 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 and the song he hears changes to a slow one, though he was not sure what she was hearing.
