Commissioned by the Carpe Diem String Quartet. Reza Vali s Calligraphies series is a set of an ongoing cycle of works based on thePersian modal system the Dastgâh which he has been composing since 2000. The basic compositional material of thework is derivedfrom a fast tempo genre called the Reng which is usually performed at the end of a traditional Persian music concert. Raak includes meter changes on almost every measure and will phase quickly between entirely homophonicsections and sections with entirely independent parts writing.
