There is this melody that my family remembers, but none of us can remember its origin. I have searched through a good number of flash games that I played as a child, as we think that is the most likely place of origin. It could be from somewhere else though.
i think i may or may have not heard this before! i think it might'v been the intro to a show. also, unrelated but the way you whistle kind of reminds me of the synths in this song, but it's unfortunately not the same song lol
(OP here) Some additional information: I am Norwegian, so there is a slight chance that a possible tv-show could be a Norwegian production. If the melody is from a flash game it would most likely have been played by me and my siblings somewhere around 2010-2016.
It seems like there are other users here who recognise the melody, so I am optimistic that we might find its origin some time!
