A series of staccato notes, sung at a single pitch.

I know this is incredibly vague but I’ve tried every means I can think of to search for this, but I have so little to go on.

I have this ear worm of a lo-fi sound and someone “singing” a single pitch (or maybe two very close ones) in the following rhythm repeated four times:

Bah buhbuhbuhbuh bah buhbah buhbah

The lengths are all short, but the Bahs are held just a bit longer like:

-….- .- .-

That first sequence of one held and for short I originally remembered as six short, but now I think it’s this.

And the. Right after it repeats four times and my brain tells me some other identifying feature of the song should begin I have a mental wall. Please, I’ve been wrestling with this for hours!
