Oboe? Harmonica? Flute? Cello? Baritone saxophone? Its all down the phasing isn't it? I hate harmonicas but when you hear it on John Barry's Midnight Cowboy is one of the most mournfully beautiful sounds ever. So, is it all in context? Even a Roland VCS3 could sound haunting played right.
I'd be over without these dreams and romantic ideals for cling to. Musically that is.
