By listening to her dual nature, she achieved a rare ability to invent mental “micro-climates”, opportunities to avoid the here and now and enter the “forever”. However, a listening, thinking mind should not aspire to the noisy confusion of large events but should introduce small ideas. These ideas then generate transformations, tiny but active, nourished by that special form of attention: “making yourself available, like paper”.

There is nothing heroic about it: “see small, hear small and think small”, she writes on those pages typed between 1952 and 1964. Even today, in her book The other rooms (2009), she invites us to listen to shadows: “People need shadows in order to rest. I’d like you to send a bunch of shadows to a friend”. Silent shadows which could be the faces of people loved and lost, but also the shadows created by the sun in a room, which become three-dimensional before our eyes and therefore a welcoming space filled with emptiness created especially for us, a space we can fill with our bodies or thoughts.

Listening to birdsong means understanding what the emptiness of the sky contains: life. Ono’s short film Outro consists of a single image coming in and out of focus. It shows Ono, Sean as a young boy, and John Lennon in a garden, a family appearing and disappearing. It is already in a void, or no longer exists, but the game of disappearing images is guided by the constant presence of the birds.

John Cage, her lifelong friend, also dedicated one of his most famous pieces to birds. The same birds who represent the sound of the skies and also of emptiness, and which represent the soundtrack of silence. We all know what idea Cage had of silence, as he even tried looking for it inside an anechoic chamber and was forced to accept that in the absence of any sound, we hear at the very least the blood flowing through our veins and the beating of the heart. Silence, the music consisting of a rest sign written on a fiveline stave, is nothing more than another anthem to listening, to the noise of the heart, the noise of emptiness, the fullness of meaning we can achieve even when there are no more words. We should mention at this point that Japan, a significant influence on both Yoko Ono and Cage, is a universe in which the kind of silence aimed at listening to the rustling of a falling leaf is much more highly regarded than it is in the West. In this fluctuating world every moment comes and goes, and it is worth remembering this even by just concentrating on the noise that consumes it.

We should remember that ancient practice brought back in vogue by Yoko Ono: the wish tree. It can be an olive tree, a maple or even a simple wooden panel bedecked with handwritten notes declaring our wishes. The artist arrives and gathers them all up, as with the Wish Tree at the 2003 Biennale, makes a small bonfire and delivers them up to the dustbowl of the world. Burning them is not intended to be an offence, but a way of perpetrating our wishes. We, who expressed these desires, have another powerful ritual at our disposal to help us achieve them: not magic, but listening. By writing down what we want, by hanging up that note, we have had to focus on an emotion, a future prospect. Nothing, other than understanding, re-reading and listening to our desire, can help us realise it. Yoko is not a witch, she is an elderly fairy, who now has the wisdom to help us listen to what we feel.
