For “The Empress”, you are writing for a full orchestra. In your own music, you often work with electronic synthesisers . Do you use pen and paper for these arrangements as well?
Yes, for orchestral pieces I like to use a pen to draw a kind of visual musical score for myself, before I write the actual score on the computer. I roughly sketch out where each instrument comes in, which parts overlap with one another, and where I would like to put contrasting elements. With electronic music, it is different. I love synthesisers, especially the ones without keyboards, because they force me to work intuitively. Many of my favourite sounds emerge from coincidences – sometimes even from glitches, such as a fluctuation in the electricity current that causes a small change in a melody. Such moments are precious. In order to be able to reproduce them as far as possible later on, I note down small codes and symbols.
Do you use notes for live performances as well?
Yes, especially for concerts with synthesisers. Turning the controls, switching patch cables, activating effects: so many small actions are involved that I make a kind of cheat sheet for myself, full of drawings, symbols and waves.
What happens to your notebooks when they are full?
I keep all of them – they are my personal archive. I have often looked inside an old notebook years later and discovered an idea which I did not pursue at the time. And suddenly, it makes sense.
