In my case as well as in my kids' cases, we looked musically talented but I believe it is an issue of effectively leveraging high intelligence in all our cases and an issue of superior fine motor skills for my DD and I. Of course, it helps that we are not rhythm or pitch challenged.
The difference between the two are clear to me although I recognize that not everyone has the same criteria. For example, I was great at sight-reading so just looked good out of the gate but would have to employ a lot of trial and error to correctly reproduce/notate a song that I heard on the radio. However, I had a friend who can listen to a song on the radio once and reproduce it on an instrument but can't sight-read to save his life. To me, he is clearly musically talented while me not so much.
