Music and Instruments. In this class, students will learn about all kinds of instruments, piano, violin, harp, guitar, drums, any kind of instrument you can think of, they will learn about it here. They will also learn how to read, write, and play sheet music. Some may find this class but a silly thing and have nothing to do with demigods, but think again, for one will never know when knowing some sort of musical information to save their lives- which most likely won't happen very often- will be needed. This class is also mainly for the enjoyment of the sound and art of music.
