Kadebostany and similar

Recently i am in love with “save me from kadebostany” in spotify which came upon to me randomly. I am looking for similar tunes where the lyrics goes off and a ,idk how can i call that part u gotta listen, smth like classical maybe but the notes keep playing in my head. Feels like those parts are trying to reach your heart and makes you think. I wanna know what is used for that part and how is the sound produced so that i can keep searching!
