I can't remember where I found these fascinating musical tests. It was probably from one of Joe Carter's long posts on random things. One measures how fine-tuned your tone recognition is. Another is about remembering a rhythmic pattern and recognizing whether a second pattern is the same one, and a third does a similar thing for a short passage whose melody or harmony may or may not have changed.
It was last week sometime, and I didn't record my scores. I was definitely above average on the pitch discrimination test, but I don't think I could be a piano tuner without a tuning fork, because it doesn't measure perfect pitch, just relative pitch. I couldn't hope to tell you what note any pitch is without a piano in front of me. I did it outside on the back porch while the kids were vying for my attention, and I still got about average to a little above average on the rhythmic and harmonic/melodic patterns, so I'd like to think I'd do better when undistracted and in a quiet place. This is something of a good sign given how little time I've had for continuing my musical skills in terms of actually producing music of my own, although I think listening to progressive rock ought to help a little
