Joan Chittister says that singing is what makes her Benedictine community a community. The singing of the group effects the unity that it represents. But since religious experience and convictions are closely tied to certain forms of music, music can also divide people. The current worship wars pit those who prefer so-called traditional hymns (German chorales and the hymnody of Isaac Watts or Charles Wesley) against those who favor so-called contemporary Christian music (CCM for short)—praise choruses often projected on a screen or wall and sung repetitiously. It’s a battle of the pipe organ against guitars and drums.
