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.

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

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 forms are not abstractions of things in the real world. They're also not symbols. I would say that my job is to invent these forms and to put them together in a way that keeps your interest, to give the forms a quirky identity so you can engage with them, so you realize there's an inner intelligence or logic.

One of the most important elements of Caio-ness I wanted to keep was that left to right reading, where one form draws you... this movement in what is otherwise a fairly still art, that sense of pulling the eye. It involves a sense of time. To me that's esoteric and magical and playful, and if a painting doesn't have that, to me it's just canvas and paint. If it does have that, then it rises above its materials.

I would say that my job is to invent these forms and to put them together in a way that keeps your interest, to give the forms a quirky identity so you can engage with them, so you realize there's an inner intelligence or logic. If you stop asking what they mean, or what they remind you of, and just look at them for 29 seconds, you find that they want to explain themselves and show you how much every tiniest detail is related to the whole.

Painting is something that requires a lot of time - it's not just one good idea out of art school.
