#1. Melody in 1/32nd tones
The first piece of this book, presents an extremely refined micro tonality. 32th of tone means that in between C and D there is a scale of 32 micro steps, each being 6.25 cents). It is not the idea to turn the audience into a "cents measure- machine", but to create a context where concentration gets wider in different levels (acoustically and semantically).
#2. Spoken text - texts: Friedrich Hölderlin
This piece is based on some fragments by Friedrich Hölderlin used by Luigi Nono in his string quartet "Fragmente - Stille an Diotima". These fragments are in the score and Nono asked specifically not to be included in the program notes, nor to be read aloud in the concert. In my piece the text is modulated through the instrument by means of different techniques. It works like a texture and should not be understood.
#3. Multiphonics choral (ppp)
A polyphonic piece made by means of homogeneous multiphonics ppp.

Fingering (staff below) and effect (staff above) in “Música invisible para flauta #1”. The pitch range of the piece is 3/4 of a tone.
Collaboration: Wobbe van der Meulen

After Batscapez he shifted his focus to visual arts, going further into exploring spatial perception and topography by making installations; architectural 3D constructions, and experimenting with photographing 3D laser writings in different environments.
Música invisible para flauta - Libro I
Invisible music for flute - Book I (2002)
The three etudes above were the starting point for a longer work: “Música invisible para flauta y bailarina / Invisible music for flute and dancer”
The idea of "Música invisible para flauta" is to re-think the flute from a different perspective, slightly away from its tradition and its literature. The organology - technical aspects of how instruments produce sound - and the exploration of different acoustical possibilities are the raw material from which the piece is built.
Extended techniques refer to new skills and a work in the boundaries of the tradition of the instrument, but mainly they aim at suggesting different perspectives to the perception.
