#1. Modulating text through the instrument
The piece for English horn is based on texts by Lewis Carroll talking about time. The text is spoken through the tube of the English horn using the whole instrument - pipe, reeds and fingering- like a modulator for the spoken-sang voice spectrum.
The subject "time" from Carroll's texts is triggering the exploration of different speeds both in speech and in percussion effects. This piece is about clocks, beatings and superposition of different psychological tempi.

#2. Extremely thin-reed glissando technique
This piece for oboe is based on a special reed, with a very long scrap. It is played with the lips away from the tip, technique which allows extremely flexible and deep glissandi -in detriment of tuning which becomes more uncertain-.
This piece explore all kind of glissandi techniques with different speeds, amplitude, duration, dynamics. The thin reed gives the instrument a rather wild character. On the other hand, the piece uses extremely soft multiphonics, which opposes the wild concreteness of the glissandi to a more unsound condition.
Música invisible para oboe y corno inglés - Libro IV
Invisible music for oboe and English horn- Book IV (2004)
The idea of "Música invisible para oboe y corno inglés" is to re-think the oboe 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.
