This could be a rant about how much I hate the popular song "Last Christmas"... but it isn't (I'll spare you). I bought myself a book of my favorite Christmas tunes, and I found myself making mistakes with "O Little Town of Bethlehem." At first I thought it was just my sight-reading skills deteriorating. Then I realized my problem.
Since that natural happens to be in the same third with a B-flat, it kept tricking me into cancelling the B wrongly. Why do they have rules about accidentals ending with bar lines if they're just going to give little "reminder" naturals? It's so confusing!
So I got out some white-out, and fixed it. Mostly because I was starting to ignore all the naturals, and there was an actual natural cancelling a B-flat near the end of the piece. It just got too annoying and confusing.
See? G-sharps, then unnecessary G-naturals, and then a REAL B-natural. Mind-boggling.
Fixed. Enjoyment of my new Christmas music is saved. Happy December everyone!
