Here is NPR’s take on what the church sings.
By and large, for what is a 4 minute segment built around a songwriting couple, it gets a bunch right. The one thing that is interesting is the complete absence of those congregations that never caught the CCM wave. It is written as if the entire chruch dropped hymnbooks for a while and then discovered them like Josiah finding the book of the law. As one of those congregations that hews to the hymnody of the church that is odd.
The best thing that they got right is the true dynamic of hymns and praise songs. Quoting Getty (the profiled couple)
The couple came to town to write songs not for individual artists, but for what Keith Getty calls “the congregation.”…There’s no definition for what’s a hymn and not a praise song. But Keith Getty says it should be singable without a band and easy for anyone sitting in the pews to pick up. And it should say something bold.
The hymn, because of its metric nature and usually simple tunes, should be immediately singable with minimal accompaniment. And because of the verse structure can actually say something. What has become known as the praise song is more musically complex. The performers sing it and maybe you get to join on the snappy chorus.
Now I’m not one to rule out the praise song (even though we don’t use them here), but what I would say is what is the intention of singing in church? Is it to emote, or is it to hear the word? Do we come to church primarily to bring what we’ve got to God, or to hear what God has for us? What you sing, even if you don’t know it, supplies an answer to that. The praise chorus can have proper places, but in my experience of it, where it is bunched up in front of the sermon, the purpose of that form is to emote and bring to God. The historic liturgy put the Kyrie (Lord have mercy) first. We praise after we’ve received the gifts – namely the mercy of the Lord. Putting praise before, as in “bringing all my worship”, is a misdirected understanding of what happens in church.
