Song detail, mimic in Scaler 2?

Hi all

James thank you for your last reply it was super helpful re Scaler 2 and Cubasis.
This is a question about what’s the correct technical or musical term for the thing we hear at the start of this song. Around the 15 second mark we hear a beautiful intertwine of two (obviously harmonically matched) different sounds.

What is the musical and or technical term or phrase for this and can a user in Scaler 2 replicate it or something similar like it?

To anyone who replies
A big thank you!

Kind regards
