"In regards to your behavioral data (the part where you had to discern whether the second tone was higher or lower than the first), you had a score of 4 Hz for perception, and 2.75 Hz for production.

What this means is, at a base tone that is 500 Hz, you are able to detect another tone that is different by only 4 Hz, and can produce two tones differing by only 2.75 Hz. Those scores are phenomenal. Tone-deaf people usually have scores over 30 Hz just to give you a reference."
