The title of Lauren Redhead’s "concerto" (2011), which connotes ‘traditional’ and historical approaches to music-making, might seem at odds with the open notation of its score. As a concerto, the performance highlights both the individual roles of the performers and the group relationships within the ensemble. This devised performance was created by the Vocal Constructivists in ‘collaboration’ with the score. As a response to notation, the performance invites consideration of all of the social activities and relationships connected with music, including composing and performing but also listening, moving, thinking, and discussing—what Christopher Small calls ‘musicking’. This work makes a concerto of the relationship between notation and individuals.
