Busy days for me, so I’ll let someone else do the writing today. This is a thought-provoking article dealing with how Biblical worship is hindered by a praise team / praise band / group of praise leaders / (choose your own nomenclature). He is not writing for or against any particular musical style, but rather focusing on three things, that singing be congregational, together, and enthusiastic. He argues that the use of praise bands hinders those things.
The hesitance of the congregational singers is an unavoidable consequence of using a Praise Team rather than a printed (or otherwise displayed) musical score; and the drowning out of the congregation by the Praise Team is due also to the fact that the Praise Team functions as the musical score, albeit one that is heard and not seen. Some Praise Teams are worse than others, of course. Some introduce more variations between stanzas than others, and such variations create even more hesitance for the congregation: Will there be an instrumental bridge between the stanzas or not? Will the same harmonies be employed in each stanza, or not? Will portions of the refrain or one of the stanzas be repeated or not? The congregation does not know—indeed cannot know—how each stanza will sound until it hears it, so the congregation sings tentatively, hesitantly, and a micro-second behind the Praise Team. The Praise Team has unwittingly become like the third grade jokester who invites you to have a seat, pointing to a chair. When you go to sit down, the jokester pulls the chair away, and you land on your backside. The Praise Team does the same thing musically; the congregation never knows (indeed, it can never know) how the Team will perform each stanza until the congregation hears it. And it can only hear it if the Praise Team is amplified to the point that it effectively overpowers the congregation.
This is a long article. But if you have an interest in thinking through the use of music in Biblical worship, you’ll need to consider what T. David Gordon has to say.
