Confession time. I can’t carry a tune in a bucket. I played trumpet in the school band for three years before I learned what the tuning slide was for. After that, I just moved it around more or less at random as the band tuned up. From what I can tell from the folks that sit around me (at church or a concert) really good singers are very rare.
So why is it that when enough people start singing together, it all sounds pretty good? I’m sure most folks have been at a concert with thousands of untrained folks singing along with the band. Do the few good singers overpower the bad? Do the good ones help the off-key folks find the right note? Do the off notes cancel each other out? Thanks!
