European Conference CEPI with Genetic Choir practice

Coming weekend, the 4th edition of CEPI (Conférence Européenne Pour l’Improvisation) is bringing together improvisers from all over Europe in Valcivières, France.

Thomas is invited to present Genetic Choir work in two workshop/presentations on Saturday. It will also be a moment to make friends and connect the WhatIIIF? initiative of a nomadic Improvisation Festival (that Genetic Choir is involved in) to the CEPI community.

If you want to pass by, look in the programme, and contact the organisers:

Next chance to do Genetic Choir practice in the Netherlands is by joining the Friday Sessions in Amsterdam (only if you already know Genetic Choir work) or come to the open One-Day workshop in Breda on 30 November 2019.

23 June: Laboratory (Non)Corpus on WeMakeTheCity2019

– klik hier voor Nederlands –

Everywhere in the world, the voice connects us. We speak, sing, listen and move each other with the vibrations of our voice. What touches us in the voice? What does the voice touch?

At a time when religious traditions are often seen as a divisive element of modern society, the Genetic Choir is developing a project that brings together both religious and secular Amsterdammers, celebrates the voice as a connecting element, and challenges city-dwellers to listen through the ears of a different context.

How is the voice experienced by a faithful Muslim, a faithful Christian, or a concert-goer of no faith? When does the voice touch something we have no words for?

Sunday, 23 June, 14:00-16:00
Dominicuskerk, Spuistraat 12, Amsterdam
free event! part of WeMakeTheCity2019

The (Non)Corpus project starts in 2019 with a series of ‘do-and-think’ encounters, to which we invite all those interested, starting with this laboratory on 23 June. We will facilitate first listening experiments and conversations, and you can work yourself with voice and sound this afternoon.

Additionally, you will have the possibility to register yourself to become more involved in this project in the autumn of this year. We are looking for a group of curious audience-collaborators who would like to follow us in our process, join the creative thinking process, and give us feedback on everything we develop.

In collaboration with mosques, churches and Pakhuis de Zwijger, (Non)Corpus organizes public workshops, meetings and concerts in October, November and December.

Become a ‘guide’ for the Genetic Choir in its search for the essence of the human voice!

Contact us if you are interested but cannot be there on 23 June (or you would like to know more): noncorpus@genetic-choir.org


Words become Music: The Edge of Language workshop 2019

Once a year, the Genetic Choir looks intensely into the wonders and pitfalls of working with language in improvised music.

The Edge of Language
6 + 7 July 2019
10:30-17:00 in Amsterdam

Vocal sounds can become words and words can become vocal music, but as a special focus for this year, we will look mainly at the latter: How to deal with existing text as a source of creating improvised music.

How much do we care about the meaning of the words? How much do we allow ourselves to play and break free from all meaning?

Join us in this workshop on 6+7 July, in which we also welcome some guests from Berlin!

dates/time: 6+7 July 2019, 10:30-17:00 

costs: 110,- exBTW (133,10 incl.) 

location: studio De Eester, C. van Eesterenlaan 302, Amsterdam
