If you drop down to F2, a seventeenth below A440, the first coincidental partial of that interval (the seventeenth)is A440. That's where you want to hear the beats, so you are actually comparing the fundamental pitch of A440 with the fundamental of the fork, and not the second partial which is slightly sharper in the string than in the fork. Therefore, your A440 will be tuned a tad flat if you use F3 to check between A440 and the fork. --- vince mrykalo rpt ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I've discovered the time i really need a vacation is just when i have gotten off vacation - ? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
