What is perfect pitch?
Perfect pitch, or absolute pitch, is the ability to identify a note without hearing any other note first. Someone with it hears a single piano key and knows it is a D, as instantly as you recognize a color. Many can also sing a named note from nothing, or notice when a familiar song is played in a different key from the original recording.
It is genuinely rare. Research estimates often cite about 1 in 10,000 people, though the true number is uncertain. It is much more common in musicians who began lessons before about age 6, and studies of conservatory students have found it far more often among speakers of tone languages such as Mandarin and Cantonese, where pitch changes the meaning of words. It also runs in families, which points to genes as well as early experience.
Perfect pitch has trade-offs, too. People who have it can find it jarring when a piece is transposed or an instrument is tuned to an older standard, and some studies have found they can be slower or less accurate at judging intervals in unfamiliar keys. It is a striking ability, but it is not a requirement for being an excellent musician. The large majority of professional musicians do not have it.
