parsifal - MLrs computer score

The ML-rs method is a music score developed in 2014 by Vicky De Visser. It is a mathematic and graphic interpretation of music. It uses the rythm of booking reading and turning the pages as division for time. The staff notation is expressive in design according different playing methods and notes are visually translated depicting different musical values inserted in the Matlab software, normally used for scientific research. The opera Parsifal from Wagner was used for demonstration of the score due to its dynamic range and diversity in instruments.

Parsifal is an opera in three acts by Richard Wagner. It is loosely based on Parzival by Wolfram von Eschenbach, a 13th-century epic poem of the Arthurian knight Parzival and his quest for the Holy Grail.

Wagner first conceived the work in April 1857 but did not finish it until twenty-five years later. It was Wagner’s last completed opera and in composing it he took advantage of the particular acoustics of his Bayreuth Festspielhaus. Parsifal was first produced at the second Bayreuth Festival in 1882. The Bayreuth Festival maintained
a monopoly on Parsifal productions until 1903, when the opera was performed at the Metropolitan Opera in New York.

The score for Parsifal calls for three
flutes, three oboes, one English horn,
three clarinets in B- at and A, one bass clarinet in B- flat and A, three bassoons, one contrabassoon; four horns in F, three trumpets in F, three trombones, one tuba, two onstage trumpets in F, 4 onstage trombones; a percussion section that includes four timpani, tenor drum, bells, onstage church bells, one onstage thunder machine; two harps and strings.

The score for Parsifal is translated according the ML-rs method developed in 2014 by Vicky De Visser.

The orignial score is available at the website of the ‘International Music Score Library Project’ (IMSLP).

Hackers & Designers installed an open walk-in publishing station at Zinefest Berlin. This publishing station invites to co-create and examine editorial design matters such as cross-media publishing. Using a thermal printer (receipt printer) as a point of departure the visitors will be the subject of the accumulating publication and simultaneously active content providers.

Thermo print has the characteristic of vanishing after a while. With an easy hack of the printer software we will capture the temporality and actuality of the event and printed matter as such. The zine content will be exclusively accumulated verbally, by speaking into a microphone. With text to speech technology the spoken word translates to text. Simultaneously an algorithm will run an automized image search on google, grabbing some of the words randomly and adding them to the zine.

going on & off the grid

Going on & off the grid

In 2017, Hackers & Designers investigated forms of dependence and obedience to technologies embedded in our daily working and living environments. In developing an elaborate hands-on program throughout the year, which peaks around July and August during the H&D Summer Academy (HDSA2017), we posed questions such as: How can we, as modern nomadic workers who often do not differentiate between work and private life, look critically at infrastructure, networks, and systems that we rely on? Are we, as steadily connected (net)workers, capable of disconnecting from existing grids? Can we rethink and build self-sustaining environments that shape our future practices in unexpected ways?

Hackers & Designers reflects on their activities in 2017 in this publication. In particular, we consider the learnings and questions raised during the investigation of processes of going on and off the grid. Taking this publication as an opportunity to reach out to the amazing beings who have collaborated with H&D in 2017, we aim to push forward self-initiation and hands-on and self-directed approaches to research – and to open up insights and discussions with other individuals and collectives.



“Snippers” is an installation that offers visitors a wide range of cut outs. Like the fresh vegetables you buy at the market, the cut outs are the basic ingredients of a (hopefully) tasty visual soup.

Torn or cut out from magazines, posters, magazines, newspapers, books, packaging and cards, the cut outs are on their  way to a new life.

The haggles invite visitors to help them bring these cut out to life in an instant collage, inspired by a story, a piece of music, an abstract composition or simply by chance.

The aim of this installation is to investigate the visual result that arises from the collaborative creation of new images and compositions starting from existing visual fragments.

Performed at:
2019 – Doek Festival, Bimhuis.
2020 – De Ruimte, Amsterdam

Les sauvages is an ongoing analogue photography project started in 2014. It visually researches the intriguing shapes the on earth seamingly dull seagulls, tranform to during flight.
