Not seeking to provoke animosity, but I am genuinely curious why it would be a bad thing to have the tabernacle in a central location or to have the choir in a loft?  It would seem logistically useful to have the tabernacle near the altar, even apart from the symbolic aspects.  And as a longtime church choir member, I respectfully disagree with the characterization of being "relegated" to a loft to provide a "disembodied" sound.  Being heard more than seen always seemed to me like a helpful way to differentiate between music as prayer and music as performance.  Mr. Feuerherd doesn't specify why these things are undesirable, apart from being traditional, as if that were a problem in itself.
