Known as the "Sybil of the Rhine", Hildegard had many visions, many of which she wrote down.They were mostly about God and his relationship with humans, the church, redemption from God, and creation. She wrote lyrical poetry which was very colourful and had lots of visionary ideas. Her music does not use plainchant like the music of many other medieval composers at the time. It mostly has small patterns of melody which are repeated many times in slightly different ways. Her music was also different because the chants she wrote were written for female voices, in a higher range than earlier chants. This made them easier for women's voices. She wrote a morality play in verse with 82 melodies.
