"WHO SPEAKS LIKE THIS" - Considering the speech a musical expression, with gesture, melody, rhythm and harmony of its own, stuttering is a medium of parametric variation. If we add the fact that we cannot find two identical stutters, the possibilities are huge. QFA is a multidisciplinary project that unites two composers, instrumentalists and multimedia artists in a show about the sound and artistic potential of stutter. This project also seeks to intervene in social reflection, valuing human differences, through a narrative that addresses the origin of stuttering, its constraints, inhibitions and myths. It intends to be an artistically experimental and eclectic project, of sociocultural intervention.
