Kaegan (21) is able to demonstrate perfect pitch during his 3rd piano lesson, thanks to the piano matching test. Did you know that 97% of autistic people have perfect pitch? (Kupferstein & Walsh, 2015). One obvious clue that it was time to test him came when Kaegan was singing the notes just from reading it, even before he heard it played from the piano. Please read about the nonverbal paradigm research study and the Rancer Method book for teaching music to gifted students, titled Perfect Pitch in the Key of Autism.
