How to make the sound from CAN'T STOP THE FEELING

[byr]

So guys been tryin to figure out what the sound that comes on around one min in the song is (https://www.youtube.com/watch?v=HmXluLvoJKY), the sound that sounds like Greyhound by Swedish House Mafia. The distorted sound that plays the iconic "da-da" in the chorus. It sounds like a chord that repeats itself, but how can it play with the other chords without clashig? Or is it just one note playing? And finally, any ideas of how to make that sound?

Thanks
