Absolute Pitch Identification: Effects of Timbre and Pitch Region
1989 · cited by 95
The study found that absolute-pitch possessors accurately identified notes but made numerous octave errors, demonstrating that they respond primarily to pitch classes rather than exact frequencies.

The analysis

Papers [0] and [1] directly investigate how individuals with absolute pitch identify musical notes, finding that they categorize tones into pitch classes and frequently make octave errors, which directly supports the claim.
