Composers such as Handel and Bach wrote their music specifically to glorify God and Jesus Christ. Some mighty works were written that involved Bible texts and stories. Musical Cantatas were written about Elijah, Samson, the Wilderness Journey, Moses, Saul and especially famous, the Messiah. This whole era culminated in the early part of the Classical era. God was given the glory during this time of music and art.
Absolute music is when the music was written for the pure sake of the music.
It was not written for any other reason other than the beauty of the music, of which God was given the glory for regarding the creation of music. All the music developed to the fullest. Full orchestras, full arrangements of musical form, instruments were highly developed into quality instruments. It was a very elegant time, music included. Very intellectual time for most people involved.
