In 1876 the first synthesizer was made and since then experiments have been made with electronics in music, especially after the Second World War. In France the 'Musique Concrète' came into being, music in which a kind of sound film was made with recorded, recognizable sounds. Fathers of these are Pierre Schaeffer and Pierre Henry, well-known composers are François Bayle and later Francis Dhomont. In Germany, electronic music began in radio studios. Werner Meyer-Eppler and Herbert Eimert laid the foundations, but Karlheinz Stockhausen became the real 'star'. He literally built up the sounds himself, from sine tones and noise sounds. Besides Stockhausen, G.M. Koenig was very important for this tradition. Nowadays, 'concrete' and electronic sounds are usually combined. In addition to 'tape music' (which does not involve performers), live electronic music is also made, often in combination with traditional instruments.
