Crazy thing is it changes with age. At around 30 I started regressing. These days I identify the tones but shifted by one semitone.
I found some papers suggesting it is possible for adults, but more difficult.

Like motion sickness with musical tones - you see one thing on the page, you have a sense for what "note" you're playing, but out comes something else.
I have perfect pitch but it's not really useful, except for noticing that my instrument is getting sharper. But that doesn't matter since you have to be in tune with the rest of the band/orchestra.
I'm currently practicing for a show with my cello tuned down a half-step, and it strongly conflicts with my ear<->muscle memory. Similar experiences when jumping between standard tuning and the Bach 5th Suite (A string tuned down to G) or Kodaly Solo Sonata (lower two strings tuned down a half step).
That doesn't require perfect pitch. Most of the YouTube musicians noted for making videos of going on sites like Omegle and its successors and taking requests which they the then play perfectly after a short listen to the original if they don't know the song do not have perfect pitch for instance. Examples include The Dooo (guitar and piano), Frank Tedesco (piano), and Rob Scallon (violin).
There's also an element of violin-specific pitch detection; if you play violin for long enough, you can recognize the specific timbre of different notes on a violin (particularly easy for open strings) which helps ground you while listening to a tune.
Because most people don't have perfect pitch, (Western) music is built on the relationships between pitches rather than the absolute pitches. So with absolute pitch, you can play something by ear; with relative pitch, you can play something by ear in any key.
Learning to think of the notes you're playing relatively instead of absolutely is already a difficult leap for most musicians, and my understanding (though I don't have absolute pitch so I can't compare from experience) is that absolute pitch makes this skill significantly harder to acquire, since you have to retrain your ear in addition to your hands.
If I were offered a choice to trade my sense of relative pitch for absolute pitch, I most certainly would not take it. I know well the feeling of incongruity when my muscle memory is stuck in the wrong key, and absolute pitch would mean I'm stuck there all the time instead of being just able to shake my head, focus on the new key, and clear my mind of the old.
The tonal speaker hears a much wider and more precise range of tones, but that precision also kind of hinders them in a way because they can't not hear it. On the other hand speak with a tonal native speaker who's also learned a non-tonal language and they can understand your mistakes (in their native tongue) perfectly, because they essentially have already untrained the tonal instinct. But I'm sure hearing those tonal mistakes feels quite jarring to them nonetheless, like when you're listening to a musician who gets a chord wrong - it just hurts.
Keyboard instruments in other temperaments (for example some Baroque tunings) may split the black keys (for example) into separate sharp and notes; sharps are used for sharp keys and flats for flat keys.
Choirs and instrumentalists who can dynamically adjust the pitch of individual notes will often do so for better tuning. (Some software instruments can also adjust tuning dynamically as you play.)
Many (if not most) pieces of music (perhaps most famously Bach's Well-Tempered Clavier) were composed with a particular temperament in mind.
A just intoned major third is about 14 cents flatter than a major third played on a 12 tone equal temperament tuned instrument (e.g., piano).
I'm not sure how much this matters in terms of having or not having perfect pitch though. Some people with perfect pitch can hear the difference between JI and 12TET and correctly their singing accordingly.
Equal temper results in each key being so many semitones above or below C Major.
Other temperaments have a distribution of pure and dissonant intervals giving different colors to each key. Certain keys would not be useful or notes would have to be adjusted to make a key sound right.
Perfect pitch is more a parlor trick than anything. Sure, it's impressive, and I wouldn't trade it away. But the most important skill that a musician can develop (and any musician can develop it) is good relative pitch, that is, the ability to identify notes once told a baseline note. But people with perfect pitch are usually terrible at relative pitch.
For example, I was in a sightsinging class long ago, with one other student with perfect pitch. Sightsinging is a course designed to develop relative pitch. The professor would play a note, say, C, tell us it's a C, then proceed to play a series of chords. The relative pitch students would work out the chords based on the C. I and the other perfect pitch student would just write out the notes we heard. The professor got angry about this, so he started starting with a C but telling everyone it was, say, an F#. Then he'd play chords relative to the C and everyone but us two would write them all out relative to F#. The perfect pitch students were totally hosed, desperately trying to transpose the notes in real-time, with our brains constantly telling us that they're all wrong, and because our relative pitch was so bad as we had relied on perfect pitch as a crutch.
This also shows up in jazz. I'm a Jazz pianist and the thing I can't do is transpose in real time. That's a CRUCIAL ABILITY for a Jazz musician. But I can't do it because my perfect pitch keeps telling me the notes I'm reading are not the same that I'm hearing.
When I occasionally visited my parent's church services, the organist, who knew I had perfect pitch, would see me and immediately transpose the organ down by one half step with a dial. I then wouldn't be able to sing anything -- all the notes in the book were wrong. I'd look up and see him grinning at me. He knew that I knew, it was just between us two. He had screwed me over.
Starting around 50 years old, my pitch has started going sharp. This is a very common effect of age in people with perfect pitch. It depends on the instrument: sawtooth waveshape instruments (guitars, violins, harmonicas) are much worse than others. I'd hear a guitar at B and it sounds like a C.
It is hard to explain how disturbing this is. All your life you could recognize colors. People around you, who only saw in monochrome, would show you a blue object and you'd say "that's blue". This amazed them, but to you it just looks blue. But then one day someone shows you an object that looks blue, but it's not. It's green. The green meter confirms it. But it LOOKS BLUE. You can't explain why this is so disturbing because to everyone else it just looks gray. This effect has a strong psychological impact too -- I've seen interesting studies on it -- because the ego has been wrapped up tightly with your perfect pitch, and now it's failing, like a piece of you going wrong.
But you also said you wouldn't trade it away. Why not? What are the positives that outweigh the negatives?
I'm not a musician, but I'm told the kid's way of naming the chords is particularly adept from a musician's point of view, and that's because the dad (a very accomplished musician) helped teach the kid. I am sure Rick has made more videos about what he did.
Eventually, you would want to teach them to map the color to the chord name and recognize the root of the chord. But that can be learned any time.
Also keep in mind that if a kid learns all the colors, you'll want to continue practicing to "bridge" over the age where they would lose the ability to recognize perfect pitch. If they mastered this at age 4, they could still potentially lose the ability if they don't practice during that period.
I dunno I have relative pitch but extremely good and can play basically anything from ear. And in a bunch of different keys because I'm not impeded by perfect pitch sensitivity.
Perfect pitch != musicality && perfect pitch != music genious or whatever people think it is. Relative pitch, good understanding pf harmony and good rhythm is much more essential.
As someone who enjoys music, from punk to jazz, I wish I could identify a C from a G as easily as I can identify blue from green.
We’re taught to use our eyes to identify colors, why not teach children to use their ears to identify notes?
It's all too easy for the top comment on a Show HN post to end up being a dismissal of the entire project - this is more the fault of upvoters than commenters, because the meaning gets subtly (or not so subtly) a lot more dismissive when it's stuck at the top of a thread. But we really want to avoid that on HN, especially when people are sharing their work.
In fact, I'd like to suggest that he's championing free range childhood by not making decisions for young people who might very realistically resent it as adults.
I know three people with perfect pitch. One of them thinks it's great (and is kind of annoying about it). The other two are constantly telling people that perfect pitch just means you're always exercising patience when your friends are singing, counting down the moments until they stop.
That sounds like a version of hell to me.
It just makes a significant difference when the context is a Show HN and the critical comment is at the top. If it is comment (say) #13 in a varied conversation, that comes across differently. This is more the fault of upvotes, as I mentioned, but it's hard to address those directly.
You can practice singing the intervals. What's a fifth sound like? You should be able to sing it. Or play it on your instrument and then sing it.
The way music schools teach this is relatively brutal and annoying, with a _lot_ of repetition and testing (eg "sing a major second above this note" and "identify the interval" questions), but I am not sure any other method works. At the same time, everyone going through an ear training curriculum does pick up decent relative pitch. This can take a year or two for college music majors, so it's not exactly a casual exercise. However, I assume the major barrier to entry is not musical aptitude but willingness to put up with bullshit, because it feels like bullshit when you are doing it.
I remember many years ago in my music lessons being shocked that some people can hear multiple notes played simultaneously. I've never found much material on learning this skill.
If you're willing to give the app a try, I bet it could actually be a pretty solid way to learn relative as well as absolute pitch. Just manually play "Red" before you start to anchor yourself. I've noticed some improvement in my relative pitch just by practicing it with my daughter. I'd be interested to know if anyone ends up using it explicitly for that purpose.
“Perfect Pitch: When you throw a banjo into a trash bin and it lands on an accordion.”
In this context the overall discussion is about pitch in the context of music.
Here the jokester takes advantage of pitch having more than one meaning in English. One of the alternate meanings is to throw.
Next the joke selects a banjo and an accordion, two instruments that are less popular and thus more likely to be understood by the general populace as being disparaged, which is a critical component for the audience to correctly infer the alternate meaning of pitch.
You put it all together and we have this hilarious joke:
A perfect throw is when a banjo is tossed into the garbage and it finds its perfect companion in an accordion that has similarly been discarded to the same trash receptacle.
