What is a vocal choir or bell choir for but ‘special music.’ Look at the nearly 2000 years of music that has been created to help us praise and reach out to our Lord and Savior. More music will be created in the future. I recall how ‘scandalous’ the Little Drummer Boy was when I was teenager in the 60s and now it is “an old standard.”
nearly 100 years ago there was a split in the Christian Church (Disciples of Christ) over whether or not there should be instruments played along with the singing or if all songs should be sung acapella. thus there are the two groups “instrumental” and “non-instrumental.
As far as "special" music is concerned ... if it is special because it is worship and praise for our Lord (sanctified) .. OK .. but if it is special because The Miller family will now sing a special ... I'm not in full agreement.
Only the Millers can sing as the Millers do.
THAT'S what I mean about congregational singing ... the people can sing no matter HOW it sounds.
It's supposed to be .. after all .. a joyful noise
