That would explain the scarcity of articles about choirs and such here on this and other Reformed sites.
The PCA church in my town has a choir and a "praise team." The "praise team" is just a handful of talented singers who lead the congregational singing.
The choir plays the same role, but also performs an anthem during the service, which is
also intended to lead others in worship (though their participation is "non-verbal").
The Regulative Principle certainly has a broad range of interpretations in the PCA, from the exclusive singing of unaccompanied pslams to the full-blown "Hollywood" sort of stuff you might pay big bucks to see at a concert.
