Soplarte arose, autumn 2008, from Charlotte van Wouwe's urge to bring sound and image together. This resulted in the first glass blowing wind instruments. Experienced musicians were asked to participate to look into the possibilities of the instruments. After several months, the quartet released its first performance at Espace Ladda and Arts Centre Vooruit.
The study went on, and after an intense period of improvisation, Charlotte brought the capabilities of the tools into a map and gave it in the hands of two composers. Each with a different perspective and their own vocabulary wrote a composition for Soplarte, who were brought several times, including at the Festival of Flanders.
Out of necessity to enrich the aural palette, new tools were developed for two people, a blazer and a voice. This double use of the instrument creates an extra dimension of intimate space. The breath of the players are connected and influence each other. The performers are moving in space during the interaction, taking distance, approach each other, and thus create a visual-spatial counterpart of the musical path that they travel.
During the residence at FLACC, a structure was designed that would allow instruments to be placed in an open space, to be played from within this very installation. The musicians move in-between the instruments and the unplayed instruments remain visual elements in the performance.

In May 2011, in continuation of the Transit and FLACC-supported project, the construction was used at “EMAF”, a festival for the audio-visual arts in Osnabrück, Germany. Here, Charlotte worked together with German musicians of the conservatory and the young composer Stefan Nagler, who also wrote pieces for this new performance. These now form part of the standard repertoire of Soplarte.
