Trying to find a sound

It’s not a “trend” as such but I’m so lost. Basically it’s on piano and it’s sounds minor rather then major and it’s like this : dun DUN dun DUN dun DUN dun duhduhduhduhduhduhduhduhduh DUHduhduhduhduhduhduh

And It has photos flashing across the screen to the beat.

I genuinely can’t find it 😭
