As a husband and a father here are my two cents...
He needs to learn his own ways to calm and soothe your little one. The way my wife calms our son is 100% different then what I do and my son responds to us differently. He simply needs to spend time with your LO without you around and from there he will learn what works and does not work for them. My wife will soosh and rock our son back and forth and he is super chill. Me, I blast Pandora and dance with him most nights, some nights...we walk up and down the stairs until I'm crazy sweaty and my son is limp in my arms. My wife won't do either, but understands that these work for us. AND I would have never known this had I not tested and tried them out.
Encourage him to try some things and be patience, BUT do not try to teach him to do exactly what you do...everything doesn't work for everyone AND he will appreciate having his own ritual with his kid.
Hope this helps!
