Yep...look up call and response in regard to melodic movement. Oshi is one of these trap/house/future/jazz producers who combines a unique mixture of sound design, modern rhythms, basic classical phrasing, and basic jazz chord voicing. To explain this in one post would require a small book. If you want to understand it you are going to have to do some research on chord voicings, melodic movement, etc. I would highly suggest Julian Bradley's Youtube channel "jazztutorial" found here:
