I am a music snob. I have all the symptoms. I like to follow the notes when I sing...most of the time. (If a seventh or a second sounds nicer in harmony than the boring DO they have written for the alto, I'll go for it.) I like when other people follow the notes, too. Because I really, really dislike missing an important chord in the sequence of chords, even if it is just one important note. And that is because I NEED to hear the pretty music that is meant to be heard here. I can get upset when they WILL NOT hit the right note. See? I got it bad. I don't let you know that on the outside of course, because my mom taught me to be polite and kind. But I long to have the song sung correctly to the point of losing interest entirely in the lyrics. This is a bad thing. I find myself hoping that in heaven, finally, they will sing it right! If there is bad or ugly music going; I really want to shut if off, now! Even if it is yours. It is very hard to be polite and bear it.
On the other hand, it doesn't go over my head when the congregation is singing a song they love and it is going well and everybody is tuned to the lyrics even if they aren't hitting the right chord. I can lay it down and go for the song as a whole and enjoy it. So there is hope for me.
Here is something good about us music snobs. When we hear good music done well, we are supremely happy. All of our enjoyment gauges are just as far right now as they were left when it was sung wrongly.
There are two kinds of music snobs, however. There are the music lover snobs who like to have it right. Then there are the folks who get so frustrated at us snobs and accuse us of all kinds of pride and things what we have never ever thought of. I contend that you are a snob, too, when you make my likes and dislikes look so...snobbish, I guess. Nobody is perfect.
But please, I wouldn't want anybody to feel offended by my opinions/feelings about music. I work on not letting it bother me when the music is hard to bear. God gave you some likes and dislikes I do not understand, too.
Finally, I am confident that when we get to heaven and it gets to be singing time that nobody is going to mind either way about the notes or chords or instrumentation. Whatever they've got there for choir and instruments is going to be the best. Out of this world wonderful, literally.
