Have you taken a look around at the congregation during the music portion of your worship assemblies? Perhaps it is different where you are, but recently I’ve noticed a trend. In several places I’ve been, very few people in the congregation were singing. I’ve wondered why.
One reason why so few people sing these days in comparison to the past is that, at least to my ear, most contemporary music doesn’t lend itself to congregational singing. Many of the tunes (what tunes?) aren’t memorable. Lyrics are often trite, overly repetitious and don’t scan well. The timing is tricky. The range and/or pitch may be outside the scope of untrained voices.
