Solitude

Oh, I know that song!
It's that song that reminds me of that naked, hopeless, resigned man on the beach. What was the song called again? It's at the tip of my tongue... Oh, yes! Solitude. That's it.
So that's what this Mademoiselle Reisz is going to play, huh? Hope it's not a crappy remix.

...and so, Edna starts listening to the song, expecting the usual pictures to pop up in her mind... But they don't.

She didn't see anything. No pictures of solitude, of hope, of longing, or of despair.
Instead, she FEELS these.

Edna bursts into tears, and she just can't stop crying. Why? Why this time and not any time else? What's so different? What has changed?

First of all, her reactions are getting more and more violent. It went from doubt to weeping to just downright crying in the middle of a piano performance. This shows how Edna is further 'waking up'. The more she sees the truth, the harsher she realizes it is.

Until now, 'Solitude' had given her a picture. Nothing more. Now, instead of simply perceiving the solitude, she feels it. Despite being in a marriage, she realizes how alone she actually is, under the oppression, not seen as much more than your average useful-for-just-a-couple-of-things human being.

Madamoiselle Reisz, after finishing her performance, comes up to Edna and tells her that she was the only one there worth playing for. Reisz seems to understand Edna, and I have my own doubts as to whether this scene might be foreshadowing something.

Before, Edna would link 'solitude' with a man. Would her view of solitude have changed after the performance? Perhaps now it is a woman staring out into the horizon, looking at the ever-so-free bird, flying across the sky as the sun begins to rise...
