With Merlijn Twaalfhoven, composer and pupil of teacher-of-composition Daan Manneke,
I participated in several of his projects.
Merlijn, among other things, exercised his projects as a result of his artist-in-residence period in the Tilburg orchestra.
But also in small concerts at the start of special events.
He utilized the voices and songs of people from the Middle East, Morocco and Central Europe.
Drinking-songs, folk-songs from different times and cultures, famous arias, medieval vocal play
sung clusters....all kinds of a wide range of vocal traditions were used, also experiments with all types of sound and extension to all the senses of both participants and listeners.

For secondary school children I worked with Merlijn in 'La Vie sur Terre ".
To this I worked as a professional singer and as a primary teacher.
Merlijn gave you a fee if he had the means and money to do so.
Alternately, the work was voluntary or paid.

From late 90's to 2010
I was a reader attached to Dedicon Studio, formerly the studio for audiobook Le Sage ten Broek, books for people who read differently ("anders lezenden").
The repertoire includes Literary thrillers, novels, children's books, informative children's books, cookbooks and short stories.
Particularly was 'Sermon to the crocodiles'(Preek tot de Krokodillen) of the Portuguese psychiatrist / novelist: António Lobo Antúnes. A book designed as a novel,
where 4 very different women do their reporting on the horrors around the Carnation Revolution. The book is even more intrusive because no punctuation was used.
Also notable was "Encyclopedia of the snow 'by Sarah Emily Miano, a novel designed as an encyclopedic work (with many footnotes and notes) about which concepts are explained by pages, full of long poetic prose, but also through songs, quotes and advertising.
It was voluntary;
the application for the job was tough as the entrance exam for the academy:
As a reader one must have:

but also the power to read out loud without annoying noises such as swallowing, smacking lips, heavy sighs or breathing......etc.

2009 I became a volunteer at Bloesem .
Bloesem  is an open house for foreign women in Tilburg Noord.
Naïma Boukou has therefore taken the initiative:
the level of violence in the district did her desire for a different way of dealing with each other:
exploit and share the large cultural differences as a source of wealth instead sharing irritation.
Classes are in Bloesem , there are mornings info on healthy living,
there is cooking, eating together, partying and drinking coffee.
For many women, Bloesem  proved important, a place of orientation, comfort and coziness.
My job was singing with the women and often with the children accompanying them.
I taught the women Dutch songs (so they could sing along with their children)
I tried to make them sing their own songs. It is their cultural heritage. which
in times of problems and worries is so easily neglected.
It turned out that (bad/naughty) love songs and lullabies were favorite;
if they loosened, it was with much laughter and sharing memories;
you saw the women become stronger, the genius in an environment that theirs (yet) was not.
The singing opens, sometimes only after weeks or months, emotions:
accumulated grief, loneliness and fear.
The women have suppressed their emotions: to not be vulnerable.
These oppressed emotions are probably the cause of many ailments that these women suffer.
Since 2010 Marya, Naima and I are also directors of Bloesem -StichtingLef.
Bloesem  works almost without subsidy and the women themselves generate an income to help it survive.
Jamilla: "Bloesem  is my life, my medicine."

In Finland I got the chance to be active in music:
Saksala Art Radius gave me the opportunity to participate in workshops in Educational Symposia:
Subjects were:

The many forms in which the exclamation "Hallelujah" is forceful

Together with Henk de Croon, there were concerts Juva, Haukivuori and Mikkeli

In 2011 I coached the choir of Haukivuori
also weekly people came to my home to practise Finnish folk songs together.

hobbies and interests
All ethnic groups;
the way people live their lives:
their history, religion and religious expression,
their language sounds and language habits, their music ,
the way they dress and live,
the way they eat and how they prepare the food,
how they feel and handle the environment .....
I like to read and write.
Language has my interest.
I like to cook and eat.
Everything related to food has my interest;
Also the cultivation thereof,
So I like gardening.
I love to make things from natural materials.
Geer Pouls, flower artist/performer,now living in Berlin, taught me how to experiment with plants,flowers and natural materials.

I control the English reasonably well.
I can express myself orally and in writing
and I can communicate well in that language.
I control the German reasonably well, but less than English.
I understand the Latin languages superficially,
I do a bit in French make myself intelligible.
On my, still very modest skills in Finnish, I work.
I desire to know me being able to express myself in that language ;
more: to be able to communicate .
From my mother tongue, Dutch, I think,
I released an excellent management.

perception and motivation

'in the pursuit of knowledge:
everyday something is added.
in the pursuit of enlightenment:
everyday something is dropped.


I believe in the voice as given to us by nature.
Unless there is a serious deficiency ,
it is, I believe, possible for anyone to sing.

Our voice deserves care and respect.

Singing is not limited to the larynx; the whole body sings.

Not only the ear, all senses are involved when one sings.

The real voice is more audible as we are less concerned with ourselves.

The voice is as personal as a fingerprint.

Through singing, the mind gets cleared.

In order to make music,(with any instrument whatsoever) it is important that people get familiar with the music of their own voice.

Singing is a language, it expresses itself in from there.

The sound of a choir singing is more attentive than the sum of its parts.

In singing the incomprehensible can be understood.

Singing makes us great beings: feet on the earth, head in the sky.

The freedom to sing in the voice, makes ourselves understood to ourselves.

Children, that receive education with music and singing, is thereby given an increasing possibility of taking in other materials.

Singing combines energy, within yourself, within a group.

Through singing, one is no longer alone.

Singing connects us with those things that fall outside the ego.

To make music, one must listen.
