By 1981, a new form of dance music was developing. This music, made using electronics, is a style of popular music commonly played in dance music nightclubs, radio stations, shows and raves. During its gradual decline in the late 1970s, disco became influenced by electronic musical instruments such as synthesizers. The first notable fully synthesized disco hit was "I Feel Love" by Giorgio Moroder and Pete Bellotte with lyrics by Donna Summer. Looping, sampling and segueing as found in disco continued to be used as creative techniques within trance music, techno music and especially house music.
