Dhruv Goel has worked as a music preparer for The Jungle Book and X-Men Apocalypse

It's Pretty esoteric to tell people that I am a 'music preparer'. But that's what it is," says musician Dhruv Goel. "You can also call me a music copyist." That doesn't mean Goel copies music. Here's what he does: Music directors send him a 'session' — a mock-up of the music they've made - on a computer software. Goel breaks it down by turning it into a printed piece of paper that details what notes will be played on the different instruments. This printed music is then sent to the studio where it is recorded by a real orchestra, instead of a digital software. "It's really a translation process," says the 27-year-old composer as he chats with us from Los Angeles, where he is based.
