@marcopolonian There is a youtube channel called The Crosbys and the little girl there has perfect pitch. They made two videos on her perfect pitch, in the first video she didn't know which one was A or which one was B, she just knew all the pitches by ear. In the next video her father taught her that, basically, he divided all the pitches to the tones and halftones and taught her the names for those. If he let her listen to 440hz and said that was A, she would learn that as A. If he showed her 445hz, that would be her A. If she was told 440hz is A and 445hz is B, that would've been the case for her too. She knows the tones by memory, but only particular tones are named to her. The rest that are inbetween are the microtones to the respective tone it is closest to.
So, doesn't matter if you change the hz. Tell someone with perfect pitch that 440hz is not A anymore, it's 442hz...their whole world won't be turned upside down by this. It'll take them longer to get used to it because they're already used to another thing, but this not because of their perfect pitch, but because of the names for the tones they were taught. Now, if every single hz had a letter or name assigned to it they won't have that problem anymore...unless you're still changing the names for it. I mean, the hz for A gets changed cause they want it to be 440hz instead of what it was originally...if there was a way to represent that tone originally, this change wouldn't have been required.
Their perfect pitch is not what's causing them a disadvantage. If they never assigned letters to them in the first place, they wouldn't have this problem, right? If like that girl in that youtube video someone had perfect pitch but didn't know what the notes were called, they wouldn't be having this problem, but they'd still have perfect pitch. Hence, the problem lies elsewhere.
Also, yea, I'm also talking about that gradual slipping of strings, I realize when I'm off-tune even when it's that gradual slipping. If you've played long enough you start being able to tell them apart. Though it does get harder to tell apart the more deeper the tone is.
You play cello? Maybe that's why you find it more difficult to tell apart when it's slipping.
"Also, you don't need perfect pitch to understand that you're not harmonizing."
That's exactly my point. That's called relative pitch, and it is an ability that people with and without perfect pitch both have to develop.
No, not talking about that. Well, I get your confusion. That was completely separate from the topic we were conversing about. I was talking about how you can tell when two notes are not harmonizing. It's like they clash, makes "wob wob wob wob" fluctuation. You don't need perfect pitch or even relative pitch for that matter to know when that happens. It'll sound like shit. When notes harmonize, you can literally feel it, their coexistance, like vibrations that match each other's pace. While the opposite of that sounds like one it trying to destroy the other. You know, like thirds...play thirds and they harmonize like angels singing. Then play two notes adjacent to each other, which would be like, seconds? lol. Play those and even non-musicians will be able to tell that that's not music. (Well, some composers like Debussy and Beethoven can make even those sound good in some fucking way. I don't know how, they probably sold their souls to the devil. If that is not witchcraft then I don't know what is.)
Anyway, you can tell apart chords? That's cool. I think I can too if I try, but my brain hurts from thinking too much so I don't bother. Since I only have relative pitch and I play violin, an instrument where you don't often play chords(if ever), I need to do a lot of calculations to figure out the chord. If I played the guitar or piano I think I'd be able to tell apart more chords through instinct alone. So far I think I can only instantly recognize a C chord. The rest I need to do a bit of a calculation. I need to hear the notes separately first, then determine which arpeggio are those notes a part of, then I'll figure out the chord...but this is a completely backwards method. lol
What you need to do is listen to the chord and understand which chord is that, then determine which notes are in that chord through that note's arpeggios. But I can't bother to learn either one of those cause I'm a violinist, and I'm lazy.
Anyway, I'll check out that article, but I'm still sticking to my words. I'm certain the disadvantage you're talking about doesn't stem from having perfect pitch, but it's something common in people with perfect pitch cause they are more proficient in remembering the pitch of certain things as an effect of them having the ability to judge which pitch that is.
If you don't know what pitch that is, you'll not remember its pitch in the first place. But if you do know what pitch that is, you are more likely to remember it. That's simple fact. And remembering something makes you more inflexible to changing what you know. So while you are GAINING new knowledge, they are ALTERING their's. And you should know which one is harder.
Now I remember the open strings GDAE because I have so much interaction with those. So even though I don't have perfect pitch, I WILL have the problem you're describing because those 4 notes are ingrained into me. But I'm more flexible with other notes apart from those, that's because those are not in my memory. I can change their determined hertz anytime and I won't even be able to tell the difference.
