Picking the right music to play to is important. The noise in the background sets the mood for what you’re doing. Even if you do just the same thing, a scene to delicate classical piano music would feel very different to one played to industrial metal, trip hop different to jazz. For most sessions I need a beat, and I usually like a depth, darkness and bassiness to the music. I prefer repetitive riffs often, and try not to go for anything too jarring.
