sentences:  Gondwana (Murail)
  
  Gondwana (1980) is a defining musical composition of spectral music for large orchestra composed by Tristan Murail using simulated synthesis to create a harmonic interpolation between an orchestrally synthesized chord derived from a simulated bell sound (inharmonic) and a chord derived from a trombone sound (harmonic).This process is meant to evoke the shifting of continents and thus the piece is named after the former supercontinent Gondwana.
