CIRCLE: Genetic Choir performs 18 June @ Sandberg Institute

IMG_2375The Genetic Choir Ensemble will perform
Saturday, 18 June 2016
a graduation work of Cathalijne Smulders from the Cure Master of Sanderg Institute, Amsterdam.
Place: Burgerweeshuis, IJsbaanpad 1-5 Amsterdam
Time: Performances will start at 12:00 and 13:00. Be welcome!
Linking nicely with Genetic Choir’s recent work at the Sarphatihuis Amsterdam where we worked with people with somatic, geriatric or psychiatric backgrounds, in this performance piece we will be working with Cathelijne Smulders and Tamara van Scheppingen in a combined exploration of the disruption of speaking and our relationship to space.
CIRCLE is an exploration of voices that mirror the boundaries of a space, an utterance, the other and a certain duration. It is part of a series of works that echo, mirror, displace and interrupt a (       ), to (dis)orientate prevailing flows of attention and meaning in favor of a more open, synthetic, porous and affectionate proposition of what (       ) can be.

Photo series of concert at dawn in Muziekgebouw a/h Ij

If you follow this link, you will find photo impressions of the Sunrise Concert the Genetic Choir gave on 11 October 2015 in the Muziekgebouw aan het Ij.

We were part of the 24hour Resonance event initiated by Merlijn Twaalfhoven, with a one-hour concert of Genetic Choir music with invited dancers between 7 and 8am and a collaboration with several World Music singers in the following music block, that was curated by Yinske Silva. Great memories!

“Echo: Labyrinth” – six Genetic Choir concerts in Amstelpark!

Labyrinth_by_snugsomeoneOn a sunny afternoon in Amstel Park you are unexpectedly invited to join a guided tour through the lesser known areas of the park. You are curious, so you join the group that has gathered and follow them into the woods. After a labyrinthine route across small paths and non-paths, you finally come to an old stone-walled space that breathes of times gone by. You are asked to wait there and listen. The space seems to echo any sound that is uttered there. Clear echoing transforms into new sounds and musical structures as layers upon layers of echoes are added. A sound labyrinth is constructed as singers create a musical journey to even further-off places. Will the musicians find their way back from the echo-labyrinth of sounds? And where is the path that leads back to the park and the normal world?


Echo: Labyrinth

BE_HACKER – Sound Performance on Friday 30th

Hacker (n.) [originally, someone who makes furniture with an axe].

“A hacker is one who enjoys the intellectual challenge of creatively overcoming and circumventing limitations of programming systems and who tries to extend their capabilities.”  Verna Gehring (2004)

hacker-redCan we ‘hack’ the sounds of a place and turn them into music? Well, that is more or less what the Genetic Choir does. No problem.
In that light, an exciting question for this upcoming performance could be: Can the Genetic Choir hack itself?

January 30th, 2015
4bidGallery, Overtoom 301, Amsterdam 

Coming Friday, the Genetic Choir will give a sound performance in 4bidGallery, Amsterdam. It is part of BE_HACKER, this year’s edition of the MiniKunstFestival.

The Silo Tapes #1

Composing vocal music in the amazing super-echo environment of an abandoned silo, in the former harbour of Amsterdam.

This is what the Genetic Choir did last month and here is the first of a number of instant compositions we recorded there. ( Maybe a new CD in the making…? )


Many thanks to
Jakub Kupikowski for the suggestion

Carolien Zwirt for the connection

and AMVEST for the permission and opportunity


You can find more Genetic Choir music on our Audio Page or on our first CD.

special concert + brunch :-)

This Sunday, 12 June at 12:00 in PuntWG, Amsterdam, we sing another, again totally different Genetic Choir concert.


This time, in collaboration with Janneke van de Putten, we emphasise the sound/resonance work of the Genetic Choir and connect it to Janneke’s background in Indian singing training.

After the performance, there’ll be coffee/tea and we’ll have a self-catered picknick/brunch with both performers and audience, for anyone who wants to join. If you come and it is possible for you, do bring a bit of nice food to share with everybody!

‘In Vocal Response to this Space’ is a collaborative composition and performance for a group of voices taking place in the beautiful acoustics of the guest working-space at Punt WG. The piece will be developed and performed with the Genetic Choir, an improvisation choir based in Amsterdam and familiar with listening and working with a minimum of sound material.

The performance creates an opportunity to experience and explore collaborative relationships between open tones of vowels and taking positions in the space. Inspired by the natural voice, being the fundament of the classical Indian Dhrupad style, the basics of the piece are long tones, sung without effort.

This is a site specific performance with a limited audience capacity. The performance is free, but bring some food for afterwards (see above) and please arrive early to prevent disappointment. Audience will be admitted from 11.40am for a prompt 12am start.

Lasloods forever!

It was a beautiful experience to sing in the Lasloods on the NDSM terrein. Thanks to both the Grachtenfestival and stichting NDSM-werf for making this possible! I hope there will soon be some recording footage to post on this site.

As far as I am concerned, we should find out if we can sing a whole concert in that space, at some point next year…   The Lasloods has an acoustic space not unlike a cathedral, but then just less predictable. It was a feast to sing there with several voices, coming from all directions.

The workshop also went very well. Thanks to an audience who dared to just jump off the edge with using their voices in this way! Anytime again 🙂


Next stop: the Open Genetic Choir workshop, 19th of September
