I've had a couple of friends with perfect pitch - you know the sort who can tell with their back turned that you've played an augmented 9th etc. One was a high school music teacher & superb show song writer and the other a show pony with a party trick. Sadly the former died early & the latter lives on playing the same party trick - excellent ears & a very, very good guitarist but with an ego larger than a Steinway.
My wife has a pretty good ear, you play it & she'll transpose it.
Myself; tin ear would be a compliment and thick ear an understatement.
the point is joy & passion in the end - I get the joy & have the passion - talent is then only a facilitator (or so I keep telling myself).
