I seem to be getting a bit better at naming pitches I hear but I think perhaps only my relative pitch is improving. Using the Pitch Hero app for the iPhone, I am spending all available free time on this experiment. I’ve found no evidence that anyone without absolute pitch has been able to acquire it as an adult. ( You need to start before age 7 they say. ) Still, if I can get a perfect score ten times in a row with this app I will be ready to retake the absolute pitch test I took.
