Stretch: Spectral Theory in the Practice of a Jazz Quartet

Piergiorgio Pirro

About this exposition

With this exposition, we share the creative process that led to the composition and performance of Stretch, a piece by a jazz quartet led by pianist Piergiorgio Pirro. We will show that introducing theoretical models and paradigms from spectralism as a “foreign body” into the workings of a small jazz band illuminates a complex network of factors at play in the band’s music making, leading to a thorough reconfiguration in which new instruments get built and played, old habits need to be unlearnt, uncommon interactions emerge and theoretical frameworks clash in practice.
