I'm no scientist but does the Doppler effect only become operative when sound source is moving? I'm confused because some of my reading on the subject lays great emphasis on the distance between sound source and receptor and others lay greater store on the movement. If distance is a factor then this is what we are talking about with offstage playing. It certainly isn't psychological - it's a fact that instruments flatten when they are played away from the stage. In the Philharmonic Hall in Liverpool, at the end of The Planets where the ladies chorus has a morendo, they were shuffling backwards (offstage) to achieve the effect. Their pitch flattened (although not in actuality) but what didn't recede was the voice of the choir conductor (also offstage) shouting out the beats of the bar as they moved away from him: "One, two, three, four, five; one, two ....." etc. Ralph R.
