Jean-Claude Risset (French: [ʁisɛ]; born 18 March 1938, Le Puy-en-Velay, France) is a French composer, best known for his pioneering contributions to computer music. He is a former student of André Jolivet and former co-worker of Max Mathews at Bell Labs. After the discrete Shepard scale Risset created a version of the scale where the steps between each tone are continuous, and it is appropriately called the continuous Risset scale or Shepard-Risset glissando. He has also created a similar effect with rhythm in which tempo seems to increase or decrease endlessly.
