Historical records reveal that the ancient Greeks played soothing instrumental music to women in labour. Music can have a relaxing effect in labour due to its ability to alter mood, reduce stress and promote positive thoughts. It can be used as a trigger for a breathing response or as a cue for relaxation. It may also be used as a distraction although this is a less effective use for music in labour. Music can be comforting not only for you, but also for your supporters.
