Why, PeteK,
What a fascinating mind you have.
I, my brother, my mother and her dad before her all have perfect pitch. Several music instrument makers in the Scottish side of the family, going quite a ways back, in fact.
It's more a genetic defect tho', than a blessing if you like serious music, as I do.
Was certified with "absolutes Gehör" back in 1998 at the Freiesmusikzentrum, Munich. The woman who registered me also opposed opening our club. I don't recall her having used a measuring tape, just a rather standard digital tuning device and a set of pianos with various tunings. As you may know, A443 is rather in fashion here, making for, oh, well I suppose that's not of general interest, sorry.
My references, just a few weeks ago, to unusually high quality turntables and pressings here in this forum, a pronounced dislike for cassettes (the best were still awful) I've mentioned upon occasion, and that charming thread a few years back where a few club members, myself included, pointed out that a video clip had to have been made in a 50Hz part of South America and not the 60Hz (was then confirmed) make for a few times the topic has come up here, at the very least.
I love steampunk and thought the reference to the violin playing Holmes (Conon Doyle also had this condition/affliction/ability) was apt. Guess not, or maybe so? The Hansaplast reference was perfect.
Oh, and, for the record, a serious riding accident in 2000 left me partially deaf.
I appreciate your, um, interest, but I'm monogamous and engaged to a wonderful man.
