None of the above. Not at all frenetic or macabre. More … pensive, if anything. Slow, like a clock ticking. The kind of music you might listen to in the dark in front of a lava lamp. (Well, I would, anyway.)
Definitely not classical. I would have recognized Beethoven’s Eroica instantly.
The first two notes of the above phrase sound like that, but slower and richer in tone. Not at all murderous, either. Maybe the kind of music you’d hear watching a spaceship as it sails through the galaxy or travels in time. But again, I’m pretty sure it’s not from a science fiction movie.
As far as I can determine with my limited musical knowledge, the beats are
ONE (rest); TWO (rest, rest, rest); three-and-four (rest). One, two (rest), and four and one-two (rest, rest, rest). Three, four.
There should be an app for this sort of thing; sing a few bars of the tune into your laptop or iPhone and it automatically finds the one you’re looking for (or a number of possibilities from which to choose). Whoever comes up with this will make a fortune!
Soundhound does just that - I haven’t used it in a while so I pulled it up - and it got “America the Beautiful” from singing and “row row row your boat” from humming, but failed on two other ones that I am too embarrassed to mention.
