Research in to Soundtracks - Rosemary's Baby

The soundtracks starts with echoing piano notes which linger making them sound strange. There is variation between major and minor notes, but mostly minor which gives it a scary tone. Guitar music then fades in to introduce her singing. The guitar tune also has a minor tone which is scary. The woman singing is very disturbing because it is supposed to be something positive, a mother singing to a child. But paired with the disturbing background music it sound threatening and strange. The guitar occasionally strums hard which is a harsh sound against the singing, I don't think this works very well because I like the gentle strangeness. I think the music builds up too much to have too much orchestra backing music, is sounds more effective very simple.  The violins in the background also sound more sad than scary. However I really do like the beginning of this soundtrack.
