All my siblings became artists. One's a novelist, my brother is a painter, my sister was a costume designer.

I was never exposed to art school. I grew up in an artist's studio. I was exposed a lot of studio time between of my father and a great painter I studied with in Barcelona. That was my art school, as Europe was.

My 20s were spent in a room, alone, mixing paints and figuring it all out.

People see so many things in the paintings. Although I never think of them, it charms me a little bit that people actually project actual scenarios on to the paintings. Hopefully that means that they have a little bit of life to them. Figuring out the rhythm, the structural element has been the key thing in this work, more than the color element. It really was the variety of different widths that lead to a certain movement, a rhythm. Otherwise I'd fall into anything that was too stripy or almost like bar codes, and it thwarted the natural flow of the painting.

I'm not such an artist type that I can't handle the real world. I read the financial pages, because most people don't talk about art.

I've been playing piano my whole life but I'd never tried to understand how compositions are made really. Try to imagine if you'd loved paintings your whole life but had never painted one. My aspiration now is just to understand. I don't have professional pretensions. I've learned so much. So many things I've been doing in the visual, two-dimensional painting world parallel many of the inner working of music - how intervals resolve into each other, harmonic rhythm, tonal things - there's a whole vocabulary that overlaps. Sometimes people see pianos in my works - that I never think.

This morning I got up early and I was glazing the paintings and they just looked so beautiful. I had a private moment of "yeah, I'm behind this." Which is all that matters as an artist, to believe in what you're doing. It sounds like an obvious thing but it takes a lot of work.
