Learning Perfect Pitch Possible As An Adult, Study Shows


Learning perfect pitch in adults has been demonstated succesfully by University of Chicago psychologists, and the training’s effects on this prized musical ability last for months.

Absolute pitch, commonly known as “perfect pitch,” is the ability to identify a note by hearing it. The ability is considered remarkably rare, estimated to be less than one in 10,000 individuals.

Among musicians, learning perfect has always been a very desired ability, especially since several famous composers, including Mozart, reportedly had it. The assumption has been that this special talent has a critical period to be established in childhood based on early musical training and that it was not possible for adults to acquire this skill.

For this study, professor of psychology Howard Nusbaum and colleagues tested how much an individual’s general auditory working memory capacity can predict the success of acquiring absolute pitch.

Developing Absolute Pitch

“This is the first significant demonstration that the ability to identify notes by hearing them may well be something that individuals can be trained to do,” said Nusbaum. “It’s an ability that is teachable, and it appears to depend on a general cognitive ability of holding sounds in one’s mind.”

The study follows up from the group’s previously published study, which shows that people with absolute pitch can be “retuned” in about 45 minutes of listening, demonstrating that absolute pitch is not so absolute.

This new study shows that people without absolute pitch have the ability to learn notes quickly as well.

A 2013 study from Harvard University researchers reported that Valproate, a drug commonly used to treat epilepsy, could effectively reopen a critical period of learning ability, allowing a person to learn skills like absolute pitch. The current UChicago study does not use medications to train the brain to learn absolute pitch skills to a comparable degree.

Pitch Perfect

The study was done in two experiments.

Seventeen UChicago students participated in the first experiment. None had absolute pitch, and all had variable amounts of music experience.

The student participants listened to notes sampled from real musical instruments through studio headphones. They heard a brief note, which was then masked by white noise. The participants were then asked to try to recreate the originally heard target note.

Another part of the experiment involved testing participants after they heard an isolated piano note, and then they were asked to identify it by its musical note name (e.g., C or F-sharp).

Experimental Perfect Pitch Training

For the training portion of the experiment, participants listened to and classified 180 piano notes, in three, 60-note blocks, and then received immediate feedback on whether they had selected the correct label for the note.

They then heard the note again. Participants showed significant improvements in note identification after the training.

The researchers were able to retest some of the study participants a few months after the training session. They found that although the participants’ learning had decreased slightly, the individuals retained most of their ability to identify notes with absolute pitch.

Hearing Working Memory Predicted

30 UChicago students, staff and community members participated in the second experiment. The experiment was similar to the first one in attempting to identify notes heard through headphones.

They were trained on 12 piano notes repetitively and received both visual and auditory feedback on their responses. They were then tested to determine if the training made any difference towards acquiring absolute pitch.

Although training adults to learn absolute pitch has been met with much skepticism, there is now evidence that it can be done.

“We demonstrate three important findings in this paper,” said Nusbaum. “First, in contrast to previous studies, we are able to establish significant absolute pitch training in adults without drugs. Second, we show that this ability is predicted by auditory working memory. Third, we show that this training lasts for months.”

The findings suggest that adults can acquire absolute pitch even without that early exposure to pitches and musical labels. However, the current set of studies cannot directly address whether this adult-acquired absolute pitch ability is comparable to the performance of “true” perfect pitch.

Ear Training Software

Ear training or aural skills is a skill musicians learn to identify, just by hearing, pitches, intervals, melody, chords, rhythms, and other basic elements of music. The application of this skill is analogous to taking dictation in written/spoken language.

As a process, ear training is in essence the inverse of sight-singing, the latter being analogous to reading a written text aloud without prior opportunity to review the material. Ear training is typically a component of formal musical training.

For accurate identification and reproduction of musical intervals, scales, chords, rhythms, and other audible parameters a great deal of practice is often necessary.

Specialised music theory and ear training software can remove the need for a partner, customise the training to the user’s needs and accurately track progress.

University music departments often license commercial software for their students, such as EarMaster, Auralia and MacGAMUT, so that they can track and manage student scores on a computer network.
