[CAUT] Pitch recognition

[Richard Brekne]

Just had my first real personal experience with this pitch recognition.  
It was really quite a strange sensation I can tell you.  I had just 
finished a run of  6 quickly tuned cheap uprights at one of the 
universities I work for and was ready to start number 7.  I sat down as 
usual and played an F-major extended chord to get a quick jist of how 
far out of tune this was whamo !.... I  <<knew>> right away the 
instrument was slightly flat !    Kind of excited,  I pulled out my 
handy dandy tunelab to proceed and sure enough the pitch was 1.25 cents 
lower then the standard used at the school.  The previous 6 had been 
tuned to 442, and this one sat fairly even at 440.75.

I was quite surprised at the experience... there was no doubt whatsoever 
in my mind ahead of looking at the tunelab display.  But such a small 
difference really for one who has had no previous personal experience 
with pitch memory, I found interesting.  Clearly tho... this was a 
learned thing.  My ear had, for the moment at any rate, become 
accustomed to the 442 frequency so well that when suddenly exposed to an 
fairly evenly tuned 440.75 it reacted.

Way cool really.
