The Mission Impossible theme, you know, the “Dun! Dun! DADA! Dun! Dun! Duhduh!” one, written in 5/4 time? That’s supposed to spell MI for Mission: Impossible, in Morse code. --… dash dash dot dot, MI. The first two notes are dotted quarter notes, 1.5 beats each for a total of 3 beats, then two quarter notes for each dot, total of 2 beats, grand total of 5 beats per measure. 5/4 time. FIND A PRACTICAL USE FOR THAT SHIT.
