Vocal Instant Composition


Genetic Choir workshops in Autumn 2018

Dear voice and improvisation aficionado’s,

here the dates and themes of upcoming Genetic Choir workshops!


Sunday, 7 October 2018

13:00-16:00 in the Badhuis, Haarlem from 13:00-16:00
contribution: 17,50 Euro / contact to reserve a place: info@haarlemoogst.nl

13+14 October 2018:

old songs new songs croppedThis weekend workshop will combine our knowledge of improvising with melodies (single or multi-layered) with using existing songs (or fragments of songs) as basis for new, instantly composed music. You can either come with a prepared song or completely blank, and we will workshop how to integrate different styles of song-singing into Genetic Choir improvisations. Those who want to purely improvise will be challenged with the task of solo improvising and story-telling. And those who like to work with their existing song will be taken on adventurous journeys of non-idiomatic ensemble improvisations with it. 🙂

Melodies are the storytellers of music. Just start singing a few notes and instantly there is a feeling/atmosphere, the beginning and clear promise of a much longer story. Melodies are also playful creatures, meaning that in bigger numbers they tend to swirl around each other, being looped and copied and transposed, creating ever-new relations and mixed identities, transforming to totally different music or ending in beautiful silences.

The Genetic Choir approach ensures that you don’t need any particular background to be able to join this workshop. Everybody works from his preferred musical style and own level of experience. The magic happens in the middle.:-)

13 + 14 October 2018 / 10:30-17:00  /  133,10 Euro (110,- excl.VAT) / Amsterdam

15+16 December 2018 – RESONANT VOICES

resonant-voices-original-vierkant-oilify.jpegWeekend workshop to explore and enrich your voice by opening your ears to the multi-layered complexities of sound, and play with it together in a polyphonic way: overtones, textures, resonance, timbre…

In deze workshop onderzoek en verrijk je je stem op het niveau van resonantie en klank textuur. Terwijl je je oren traint, train en open je je stem. We werken en componeren met open klanken, andere textuurrijke geluiden van de menselijke stem, klank-clusters, resonantie-ruimtes, etc… (meer info in het Nederlands, klik hier en scroll naar beneden)

A workshop on improvising with voice colours and resonance

The voice is a special system in our body – it is eager to learn and it reacts to its own sounds. By opening your ears alone, your voice can learn to become more free and resonant.

This workshop will improve your voice by focussing for one weekend on the aspects of sound that are often overlooked: resonance, texture, timbre, overtones. Whatever level of experience you are at, this work will increase your singing skill: Beginners will be surprised about the round and resonant sound that their voice will gain, and the ease of singing that comes with it. Experienced and professional singers will improve their ability to do precision-work in this area: Using timbre and textures to compose music, solo and ‘en groupe’. How to create both soothing carpets of sound and grinding dissonant cluster-chords. How to develop the music together, how to dissolve your voice in a sea of sounds, but also make clearly defined choices and go your own way, if you are inclined to.

In the cold month of December a workshop that will warm you up from the inside and get your whole body to resonate!

15 + 16 December 2018 / 10:30-17:00  /  133,10 Euro (110,- excl.VAT) / Amsterdam

Your audience guide to the Odyssey this Saturday

(1) Banner invitation 2This Saturday, 14 July, the 10 hour concert and reading of Genetic Choir and the International Readers of Homer on the Over het Ij Festival will finally happen!

As we can imagine that not everyone wants to spend the whole ten hours with us, here a guide to some great moments in the story & music (of which there are many!):

+/- 12:00 Opening (always a great moment, with probably the most famous lines of the poem, read in ancient Greek)

+/- 13:10 Goddess Calypso is told by Zeus to give up her lover Odysseus (which she is not taking lightly).

+/- 13:30 Poseidon rages and conjures a storm that leaves Odysseus shipwrecked and lost in the ocean.

+/- 15:00 Odysseus taunts the Cyclops and is cursed to end up with his ship even further from home, thrown back and further back by a bag of winds.

+/- 16:00 Odysseus enters the underworld to meet (amongst other ghosts and dead warriors) the ghost of his mother that he longs to touch, but can’t.

+/- 17:30 How to welcome a stranger (Odysseus arrives at Eumaios house) “One must honor guests and foreigners and strangers, even those much poorer than oneself.”

+/- 19:20 Penelope and Odysseus meet again after twenty years of being separate, while Odysseus keeps playing hide and seek with her. (What a relationship!)

+/- 21:00 Penelope puts Odysseus to the test about his true identity before she accepts him again.

+/- 21:30 Odysseus slaughters all the suitors and their helpers to reclaim his house (it feels almost Klingon, if you know the reference ;-))

+/- 22:00 Last sentences of the poem + musical Epilogue by Genetic Choir, after singing for 10 hours, to sum up and close the experience of this Amsterdam Odyssey.

If you want to read yourself a 3-minute fragment, you can still give yourself up:

PLACE: Nieuw Dakota, Ms. van Riemsdijkweg 41b, Amsterdam

The performance is invited by and created in collaboration with Giorgos Gripeos’ installation “an odyssey”.

It is a free event, you are welcome to come anytime during those 10 hours to experience it. And you are also invited to participate actively as one of the readers of this epic tale!

Saturday, 14 July, 12:00-22:00
Location: Nieuw Dakota , Ms.van Riemsdijkweg 41b, 1033RC Amsterdam

For the Odyssey reading, the Genetic Choir will perform 10 hours of live music, using their unique form of vocal instant composition. Reminiscent of an ancient Greek Choir, the singers comment on, foretell and mirror the events of the story, reacting to the verbal rhythm of each reader. To capture and transmit a sense of the epic length of Odysseus’ journey, the singers are a constant witness to the events and stay ‘on board’ from the first sentence to the last

May ’68-inspired trash opera performance a re-sounding success


On Saturday 9 June 2018 two members of the Genetic Choir, Ralph de Rijke and Jeannette Huizinga, joined percussionists Robbert van Hulzen and Dirk Bruinsma and dancer Michael Jahoda to take part in a structured, but largely improvised opera whose lyrics were drawn from the Situationist graffiti and slogans of the May ’68 uprising in Paris. Music was played on trash items like truck springs, pickaxe heads, and metal sheets. The opera – part of MayDays, 3 evenings of art performances curated by The Warp – was held in the Kunstkapel in Amsterdam, a circular space with some challenging acoustics. 🙂 The performance was a great success, and the group plans to continue shouting, singing and banging things under the name Schroothoopera. The first such appearance will be at the Trashlesstival at De Ceuvel on Saturday 7 July 2018.
