Absolute pitch: a completely useless skill, which having can in some cases even be detrimental. While being very hard to impossible to acquire. So naturally I will stop at nothing trying to develop it :)

A couple of months ago, this paper made the rounds: Absolute pitch in involuntary musical imagery [0]. In a small sample group, nearly half the time (44.7%) when someone was asked to sing their current earworm, were they perfectly in pitch. Random chance would be 8.3%.

It’s a fun thing to try for yourself. Just hum your current earworm into a voice memo, and check the correct pitch against the recording of the original song. You may discover a skill you never knew you had, implicit perfect pitch on involuntary music!

Trying to make this more interesting, reproducing a particular song on demand (there’s references to that too in the paper - it also works better than random chance, but less so than the involuntary kind), I find it works best for songs that start off with a single note, preferably sung. Or then at least you can immediately check whether you were right, e.g. “Tom’s Diner”. I’ve been having a lot of fun humming the first tone to Laufey’s cover of Sunny side of the street [1] whenever I open YouTube. I’m more often right than wrong, and if I was wrong, I can just listen to the whole thing to brighten my day anyways.

This post isn't compelling to me.

> a completely useless skill

It's probably an overrated skill depending on the musical task, but to say it's completely useless is really ignorant. Nearly anyone who studies music at the university level or above would find this statement ("completely useless") to be wildly incorrect.

> Random chance would be 8.3%.

A random human won't sing off the cuff with their tonal center magically quantized to one of the twelve keys in our modern western tuning (Equal Temperament).

This criticism isn't compelling to me.

The smiling emoji at the end of the first paragraph indicates that these statements were made somewhat in jest, or perhaps exaggerated. Of course some uses can be found for absolute pitch. I saw one a couple weeks back, when Jacob Collier was tuning the audience choir to lead into "Somebody to Love" played on the piano. But, hadn't he had absolute pitch, he might just have picked up a reference note from the piano or his in-ear monitors, like a filthy commoner. Usually when making music, having good relative pitch is required, and a reference instrument is mostly handy, making perfect pitch somewhat redundant. But do tell what you're doing with perfect pitch, I'm curious.

And on curiosity, I went to your website and randomly listened to "The Fugue Song" [0]. Really loved it! Very nice moment when the singing comes in, repeating the phrase from the fugy guitar intro. Good song! (I'm a total sucker for Nina Simone's "Love Me Or Leave me", do you know that? A song where she's inserting some counterpoint improvisations in the middle). I'm listening to a bit of "Hiss" now.

> 8.3%

Rounded to the next semitone of course, I left that detail out, it's in the paper.

It's just an anecdote, but: I remember playing in a band with an amateur musician friend who told me had perfect pitch, and it was "very annoying", according to him, when we transposed songs to fit our voices. They just "sounded wrong" to him. He would make beginner mistakes since he relied on pitch memory rather than listening to us to know what to play/sing.

I have no idea how it works in general, but it seems like it was a problem for at least this one guy.

xD Well I didn't expect it to go there. I don't know that song but I'll have to listen to it when I get home.

I don't have perfect pitch but it's not too hard to imagine what I could do with it. For me, it'd simply make a lot of tasks faster. I've spent a lot of time throughout my life transcribing music. I can do it relatively quickly but there's lots of moments where I have to confirm things, or poke around notes finding the matching notes, struggling to clarify shades of a chord based on the presence of notes.

Reading music will be easier for people with AP, especially in singing situations. Even if you're a pianist it will still be helpful. There are a few Marc-Andre Hamelin interviews out there where he describes some of the advantages. It's easier to read music if you know immediately what it's going to sound like. Again, this is possible with relative pitch, but it's just more work and slower.

Arranging and composing away from the keyboard will be much easier with perfect pitch.

As time goes on, it'll be less important, most likely. And yes, there are some downsides obviously. In my final aural training class in music school, we had a competition at the very end of the year for fun. It came down to a team of 3 I was on vs. a team of 3 that had a guy with AP. The final task was to sight-sing a musical 'round' (a composition where the melody repeats in the various voices at different points in different voices overlapping each other). The guy with AP actually ruined it for his team. They mistakenly chose him to finish the round instead of start it. Mid-way through their performance, the pitch on their team had drifted so heavily they were in-between notes on the piano when he took over. He tried to sing 'relative' to everyone else but it was so hard for him. It was so unnatural for him to sing out of key, he couldn't do it; it sounded really bad. Great guy though and a ridiculously good violinist.

Why is that relevant? Whatever pitch they pick would fall into one of the 12 buckets, even if it isn't precisely the correct pitch.

It's not called "in-the-ballpark" pitch, it's called perfect/absolute pitch. Being up to a quarter tone off is a large error in music. Thinking of pitch in terms of 12 buckets is not musically useful. The vast majority of music is based off consonance where being even a few hertz off means unpleasant dissonance. TLDR: Thinking of pitch as 12 buckets is mostly irrelevant.

Less than 12 to my ears.

I always observed that the number of random non-musicians who can get it right using the "major" handful of those twelve keys is remarkable enough to be considered.

Since those are the only 12 notes so many people have been hearing from every direction for so long, and truly confined to not more than a few of the major keys that are "dominant" as a result of modern instrumentation, it gets ingrained in the psyche and the notes are almost memorized by frequency. With nothing in-between, so that's what they reproduce without any training. Or can have a more sensitive ear for out-of-tune notes than an actual music student of a number of years.

I agree, it doesn't happen magically.

It just happens about any time naturally.

This is really a fun skill to learn that you have. I've had a pretty good ear for relative pitch since birth, which my music teachers picked up on right away (I could play songs "by ear" after hearing them a couple of times), but I struggled with blind pitch in the mornings... until I realized that, for whatever reason, I can hear the theme from Zora's Domain in perfect clarity in the proper key.

I used that to fake absolute pitch for a while in college, then explained to my voice coach what I was doing, and he looked at me like I had three heads. I'll never forget it. :)

I find I can recall something with accurate pitch, but the "memory" of that pitch fades over time. Whatever my current favorite song is, I can hum it at the right pitch. But, if I were to try to do so a month later, it will probably be transposed a bit because I somehow lost that sense of the exact correct pitch. My idea of what "feels right" in that regard somehow fades, or something...
