Music had always been the handmaid of the Roman liturgy.
There's nothing stupider than bursting into song for seven seconds and then falling silent again.
Even Catholic parishes today are not wanting for talent. But no serious singer or organist will get anywhere near the typical music program, at least if he wants to retain his self-respect.
The pastor of a parish will typically have no education in the chant or in music, and he will hire the first music director who walks through the door.
Then suddenly the Roman liturgy disappeared as we knew it.
Never have so many recordings of the great Masses and motets been in wider circulation.
