Exploring Structures and Flow this weekend

For those who thought that “Flow” and “Structures” are opposites of each other, come join our upcoming Voice Improvisation workshop to see how they are completely intertwined!

Take river deltas and city traffic: flow creates structures (by itself) and structures create flow. But sometimes, certain structures block the flow in improvisation. So when does that happen, and how can we prevent it?

Sing, research and play with Genetic Choir singers around this theme this coming weekend in Amsterdam!

When: Saturday and Sunday, 7+8 October, 10:30-17:00

Where: studio de Eester, C. van Eesterenlaan 266, Amsterdam

How much: € 110,- exBTW (€ 130,10 total)

How: Inscribe via workshops@genetic-choir.org

Genetic Choir Workshops in Prague and Amsterdam in 2017

After the summer, our workshop season starts again, with workshops in Amsterdam and Prague. There was a Genetic Choir workshop in Prague six years ago and when the www.hlasohled.cz asked Thomas back for this autumn, we found this video they made then, which is still really fun to watch. If only for the attempts of Thomas to explain it all  🙂

See below or on the workshop page all upcoming dates for having your own experience.


A day of simply celebrating music making the Genetic Choir way: Some crisp training of the principles, but most of all lots of singing and creating pieces!  What is the Genetic Choir way of working?  Click here for more info.

7 + 8 October 2017 – STRUCTURES & FLOW

structures+flow3Flow is probably one of the most important aspects of improvising together: when there is no flow and vivid engagement in the moment, up comes thinking, doubt, trying to do it ‘right’ – all the things we need to avoid when creating music on the spot.
Definition, however, seems just as important: How to define, sharpen en deepen you material while working with it on the spot, so that it doesn’t go in all directions at once? How to tame the river of inspiration and let it flow at the same time?

One thing that can help with gaining more definition are structures: self-imposed limitations to your improvisation. We will find that limitations and structures are not the opposite of freedom or flow, but that all these aspects need each other and are always present, whether you want it or not. But what sort of structures/limitations work well within improvised performance? What is smothering the improvisation or numbing it, rather than bringing it to life? There are many ways to create frames or structures for improvisation.

The ambition of this workshop is to find out – through learning by doing – what works best for you to set you up for singing and composing in the moment.

Two full days, 10:30-17:00  /  110,- exBTW (130,10 incl.)  /  Amsterdam / Inscribe via workshops@genetic-choir.org

18 + 19 November 2017 – RHYTHM & TIME(ING)

“Marking and moulding the time that is passing”, that is one way to define what you do when working with rhythm in improvisation. Looking at it from a Genetic Choir point of view, we are less interested in counting rhythms and more interested in the simple exhilaration of singing in ’many times’ (polyrhythms) or the thrill of falling together in the ‘same time’. We will explore how we can let complex rhythms appear, how we can groove together and groove on our own, in short: A weekend to become a true rhythm animal without ever counting a beat!

Two full days, 10:30-17:00  /  110,- exBTW (130,10 incl.)  /  Amsterdam / Inscribe via workshops@genetic-choir.org

Underground Concert Repercussions

Such a big project, such great moments!

The Amsterdam Central Station concerts of Loop-Copy-Mutate felt like a celebration of the unique Genetic Choir way of bringing experimental/modern music to wider audiences, by involving them in the concerts.

And we were so happy that this organisational monster of a project went smoothly and to such great results in terms of audience numbers and artistic result. A BIG THANKS again to everyone involved!

We will come soon with our own concert registration, but for now you can read these articles about the project in the Dutch Newspapers Het Parool and Volkskrant.

You can also look at the below video report made by our hosts, the Noord/Zuidlijn people themselves.

More background info about the Loop-Copy-Mutate project can be found here.

“Baden”: Genetic Choir performers collaborate in Cure Park, Amsterdamse Bos

This Friday, 7th of July, you can experience a very special performance-on-location involving Genetic Choir singers during ‘Cure Park’ in the Amsterdamse Bos!

Baden (Bathing), by Cathalijne Smulders

7 July 2017, 16:00 & 17:30 

Place: close to the Amsterdamse Bostheater, on the beach (‘strandje, naast de kabelkaan’).

A map for when you are in the park is here.

The Genetic Choir collaborated before with Cathalijne Smulders in the performance CIRCLE which also was based on working with people with a speech-handicap. ‘Baden’ is a development on the same theme, now also involving movement and dance.

In Baden (Bathing), Cathalijne Smulders works with people who have difficulties with language, speech or gestures as a result of brain damage. In her performance Smulders illustrates the sense of disorientation that occurs when words lose their meaning. Speakers suffering from aphasia or spasms describe their surroundings. Their words and actions are distorted by hesitations and physical reflexes. This distorted speech subtly influences the way in which we perceive the surroundings.

The influence of impeded speech on perception is reinforced by the presence of an improv choir and dancers reacting to the speakers. They support the speakers by mirroring or slowing down their words and gestures, or alternatively, make them sound more fluent. During the performance words make way for sounds, and the emphasis shifts to more physical, sensitive and fragile forms of exchange. When words lose their meaning, a new form of exchange originates.

About the Cure Park festival:

Cure Park is a contemporary health resort that will pitch its tents this summer from June 4 to July 16 among the trees of the Amsterdam Forest. Centered around the Bostheater, Cure Park brings together over 30 artists, creatives and thinkers with audiences and care professionals in a multidimensional program, comprising installations, experiments, interventions, workshops, exercises, lectures, performances and films. www.curepark.nl
