> absolute pitch, the rare ability to identify a musical note like F# just by hearing it, can be a massive benefit to a musician. you can learn the skill in a matter of weeks, but it can only be acquired before the age of 7. only 0.01% of people end up learning it in time!<p>This seems to be a very problematic paragraph. In particular:<p>> it can only be acquired before the age of 7<p>I'm doubtful about how true this is. I can't find anything backing up this claim (unless you count "being born with synesthesia" or "being blind at birth" as "acquired"); the closest I can find is Mozart having demonstrated this ability by age 7.<p>On the contrary, this seems like the exact sort of thing someone could readily memorize well beyond that age (maybe not <i>perfectly</i>, but within a given margin of error, sure), much like one might recognize a given tempo or a given shade of orange. It's <i>hard</i>, but with practice it's possible.<p>In fact, most people are able to recognize the pitches themselves; even amateur singers (and non-singers entirely) can sing songs they've heard in approximately the right key, and the average person can usually recognize when a song is pitched up or down relative to how it's "supposed" to be (this is one of the common traits for both nightcore and vaporwave: shifting the pitch up or down, respectively). What's missing here is the ability to actually name that pitch, but just because one can't vocalize what the brain recognizes doesn't mean recognition/identification doesn't happen <i>at all</i>; it just happens through other mechanisms (like singing/playing that note again later).<p>In my case, I certainly don't have "absolute pitch" as defined by that paragraph, but if you sang something to me and asked me to play it on a trombone I could probably do it without having to fumble for a reference note. Worst-case, I can produce a reference note in my head (usually B-flat, since most brass instruments nowadays are keyed to it) and extrapolate.<p>And on that note:<p>> can be a massive benefit to a musician<p>I'm <i>very</i> doubtful about how true this is. Usually what's far more critical is <i>relative</i> pitch - that is, the ability to accurately recreate a pitch in relation to some arbitrary reference pitch (e.g. singing/playing a note in a chord or scale). Absolute pitch (in this specific sense, rather than the more innate/internal sense I described above) helps for music transcription, and... that's about it. Being able to sing a perfect 440Hz A does jack squat if that A's supposed to be in an F-major chord/scale.<p>If anything, absolute pitch recognition can make it <i>harder</i> to perform in an ensemble, or to perform music with a different pitch convention other than A=440 (e.g. Baroque music), or to otherwise be able to adapt one's pitch to match the actual music to be performed.
