I worry about technical details - did I mix the cello half a decibel too high? Things like that.

In the mid-2000s, I kind of accidentally became a music editor.

No one's being precious about their music. They want the film to be great. And that was the huge lesson for me along the way to be a filmmaker. And yes, I'm leading the music department kind of thing and that responsibility with the music is with me, but really that job is one of many.

The realisation that, depending on where we changed from one note to the next in a melodic line, the music could subtly influence the entire meaning of a scene in so many ways was like a door opening to this amazing new world for me.

A lot of the music editing job is communication and working out what a director really wants the music to be.

I find that I love so much stuff and respect so many people who work in this industry and music in general. I've kind of learned that I've got to just stick to what I can do and try and do that really.

I studied music all the way through college, but as soon as I graduated from university, I got straight into London and got straight into film music. So really my experiences have been being around the orchestras in London and being around the people who work in film music.

For me, I work very self-contained. It's literally just me sitting in a room doing it until the very end of the process when other musicians come in and instruments are recorded.

I've been able to have broad kind of education and all sorts of different music and a lot of kind of films and also different styles and genres. And so, all of these things have influenced me along the way and I take a little bit from everything I do. I've been lucky to work with a lot of great people and learn from them.

For me, anything can be music! I can get huge enjoyment and be moved totally by the purity and perfection of some Renaissance polyphony, but equally I can feel emotion in the expectant hum of a big old guitar amp just before the strings are hit.

I think after everything in the whole process of filmmaking, temp scores are great if you use them for what they're good for, if you use them for that early stage of support for things.

With the great people that you work with, it's that they're never giving up and they're never thinking something's finished until they've really, really run out of time. They keep pushing in case there's a better idea around the corner.
