Dave Williamson’s God Singers joins these other must-haves where the specific subject of worship-leading choirs is concerned. Every possible topic that should be covered in a book of this nature is here. Biblical support for the use of choirs in worship? Check. Lots and lots of practical how-to’s for getting the best sound out of your singers? Got it. Sociological discussions of issues inherent in corporate ministry, even ones peculiar to choral singing? Yep. Stylistic techniques for transforming your choristers into a black-gospel choir, a rock choir, or a modern-worship choir—i.e., what to do with vibrato, vocal licks, and syncopation? They’re here. Helpful appendices from Williamson’s 40 years in the biz? Nine of them. Consider purchasing the (condensed) singer’s edition for your choir members and the (expanded) director’s edition, which includes a CD-ROM of ancillaries, for yourself. Highly recommended.
