Carpets kill the chant. Trying to combat the effect of carpets in churches by installing more and better loadspeakers and so on obviously won't help the Chant either - amplification can only be used effectively by pop-style music. One reason it is going to be difficult to revive the Chant - or any music in accordance with the Church's enormous and wonderful tradition - is carpets. They will make it sound awful.
Rip them out!
