I think a good photographer, and you are one, will consciously or unconsciously respond to and incorporate what is inspiring him or her at the moment the camera takes its picture. So these influences will inevitably be reflected somehow in the picture.
What especially struck me about this picture was the wonderful sweep of her hair along her right side of her face, and underneath and then back over her left shoulder. Every time I look at this I can't help but see the bass clef of musical notation. Her look has the sort of tranquility that comes from a peaceful meditation on something which she finds pleasing to contemplate. I think she is a good enough model to be able to find within herself pleasant emotions that she can then bring to the art without explicit external cues, but I also think it likely that the session was arranged in such a way as to be conducive to producing the best pictures possible. So there was something in the background that assisted in setting the mood here. The logical guess is that music was playing. Perhaps the title gives a hint that this was so. A fine art was part of the background, and she does not have to gaze upon it to enjoy it. She can shut her eyes and listen. There are only two such arts: music and poetry. Again, music is the more logical guess.
Now, I wrote earlier "she must be", but of course, that is an exaggeration. It could be something else entirely. But I like to imagine more than what the art is literally revealing. It's part of a fantasy, that somehow I the viewer can be there too.
