Maybe it’s like looking at a delightful scene and taking a photo of it, only to find powelines all over the sky and telegraph poles growing out of people’s heads. The brain seems to just filter this stuff out.
Having my basses correctly intonated gives me a sense of satisfaction and I think I unconsciously enjoy doing it, even though I might harumph and act like it’s a nuisance. However, given that I’m not a soloist and the dusty end is just that, do I really need to bother with being precise? I don’t know, but I’ll keep on doing it anyway.
