She expressed her sadness through her song, her sorrow from inside for not being understood by her husband.
“I’m sitting here weeping while the hours pass so slow
And I know that in the mornin’ I have to let you go
And you’ll be just a man once I leave to know
For these past few days someone I don’t recognize ”
She couldn’t finish the song, stopped by sobbing.

Looking up the hill tonight
When you have closed your eyes
I wish I didn’t have to make all those mistakes and be wise
Please try to be patient and know that I’m still learning
I’m sorry that you have to see the strength inside me burning

Where are you now, angel now
Don’t you see me crying
And I know that you can’t do it all
But you can’t say your not trying
I’m on my knees in front of him
But he doesn’t seem to see me
But all his troubles on his mind is looking right through me
And I’m letting myself down deciding is falling you
And I wished that you could see I have my troubles too

Lookin’ at you leavin’
I’m looking for a sign

The film doesn’t tell their names. They are just “Guy” and “Girl” in the film. They met each other through music. This scene was when they played and sang together for the first time. The girl took the guy to the shop she worked for part-time and showed him the piano she had been dreaming for( also the one the guy bought her later on before he left). Then here came the beautiful song- Falling Slowly

I don’t know you
But I want you
All the more for that
Words fall through me
And always fool me
And I can’t react
And games that never amount
To more than they’re meant
Will play themselves out

Take this sinking boat and point it home
We’ve still got time
Raise your hopeful voice you have a choice
You’ve made it now

Falling slowly, eyes that know me
And I can’t go back
Moods that take me and erase me
And I’m painted black
You have suffered enough
And warred with yourself
It’s time that you won

Take this sinking boat and point it home
We’ve still got time
Raise your hopeful voice you had a choice
You’ve made it now
Falling slowly sing your melody
I’ll sing along
