Say you have a client who tells you, "I want you to make me an original music. But I want it to sound like John Powell's This Is Berk from the movie How to Train Your Dragon." And you have access to the score of it. What do you do? What is your process and how do you try to understand a piece? I think being able to write an original music that sounds like the one you're analyzing means you at least understand something about the piece. What do you look for? Instrumentation? Key? Form? Harmony?
