Absolute pitch can be learned by some adults.

Area of Science:

• Auditory Neuroscience
• Music Cognition
• Perceptual Learning

Background:

• Absolute pitch (AP) is the ability to identify musical notes without a reference.
• AP is traditionally believed to require an early critical developmental period.
• Adults show limited AP improvement with brief training.

Purpose of the Study:

• To investigate if adults can achieve genuine AP levels through extended training.
• To determine if adult-acquired AP is comparable to naturally occurring AP.
• To explore the mechanisms and limitations of adult AP learning.

Main Methods:

• Eight weeks of explicit perceptual training designed to improve AP.
• Post-training assessments using diverse timbres and octaves.
• Analysis of response time and accuracy to rule out alternative strategies.

Main Results:

• The best adult learners achieved genuine AP levels after training.
• Performance was comparable to lifelong AP possessors across various measures.
• Improvements were retained for at least four months.
• Response time and accuracy data refuted relative pitch strategy explanations.
• Most participants showed only modest gains, indicating learning difficulty for some.

Conclusions:

• Extended perceptual training can lead to genuine AP in some adults.
• Adult AP acquisition is possible and can be indistinguishable from early-developed AP.
• These findings challenge strict critical period hypotheses for AP development.
• Near-perfect AP may be attainable only by a subset of adults.
