So I just finished watching Eagle Eye less than five minutes ago, and I'm being overly anal on this point,
but...
alright, so movies about computers running amok and developing a personality in addition to already insane AI and all
that jazz is already providing impossible situations...
But you know at the end where Aria plans to assassinate the President by using that crystal activated by sound waves embedded in that kid's trumpet, and how when it hits the high F it's gonna blow up the area and stuff, and Jerry stops the orchestra playing right before they hit the FREEEEE! (and the home of the *blow up*)
but that high F isn't the first time you hear it in the Star Spangled Banner; it's also the note for
"glare" (as in rocket's red glare)
Furthermore, if you take harmonics into account, wouldn't all the F's resonate somehow to trigger the hex
crystal thing?
Maybe it's like breaking glasses, singing at the harmonic of the glass won't break it until it's at the right intensity, but it still doesn't change the fact that the high F in the piece occurs much earlier than where most people think it is.
