Snapless, very interesting observation. I played a musical instrument, successfully I may add, when I was growing up. Now that I think about it, whenever I was learning a new song, I would play it over and over until I got it right. My private music teacher would get frustrated because I couldn't make a mistake and keep playing. I'd have to stop and try the refrain again until I would get it right. Your observation totally makes sense to me! Thanks!
