Common themes of Christian music include praise, worship, penitence and lament, and its forms vary widely around the world.

Believing that complexity had a tendency to create cacophony, which ruined the music, Gregory I kept things very simple with the chant.
The singing of the Eastern Orthodox is also generally unaccompanied, though in the United States organs are sometimes used as a result of Western influence.
Some of the most well-known exponents of such organ compositions include Johann Sebastian Bach, Dieterich Buxtehude, George Frideric Handel, François Couperin, César Franck and Charles-Marie Widor to name a few.

By the 1990s the genre had eclipsed classical, jazz, and new-age music, and artists began gaining acceptance in the general market.
Other famous artists include Chris Tomlin, Casting Crowns, Amy Grant, and Skillet.
