What were the 3 basic purposes of art music in the Renasissance

(1) worship in both the Catholic and burgeoning Protestant Churches,

(2) music for the entertainment and edification of the courts and courtly life,

(3) dance music.

i got this answer from a really friend, and it was right.

hope this you like it me and a special to that dude!

artists need to create a realistic interpretation so that people in general can relate to the artwork. for a common people, an artist's impression gets increased only if he can create something which would look realistic. an abstract is difficult for a common people to understand whereas if a person can draw a girl with simple pencil sketch and if that looks like a real figure then the latter will be praised more than the former.
