The workshop is free. It is an invitation to practice reading in chorus on the compositions of the German poetess Nelly Sachs by starting from the molecular technique and put forward by Chiara Guidi in her vocal research path. Exercises will be carried out to give expression and cadence to the individual phonemes in an orchestration perspective. At the end of the third day, the choir will converge in the reading of Letters from the Night, with Chiara Guidi, staged on Saturday, July 14 at 22.15 at the Roman Theater in Lecce.
