Step-by-step explanation:
Gregorian Chant, named after Pope Gregory I, is a form of plainchant that evolved over centuries and is associated with the liturgical music of the Catholic Church. Despite the medieval legend that credited Pope Gregory I with creating all known Gregorian Chants, the chants actually developed gradually over time. While Pope Gregory I did play a significant role in promoting and organizing the chants, he did not compose all of them, nor did he write the harmonies and instrumental parts. The development and spread of Gregorian Chant was influenced by factors such as religious practices, political stability, and the invention of the Gutenberg press, which facilitated the distribution of music.
