Monique, also named Tina or Luna, is writing a song. She looks like she is deep in thought. She isn't performing, she is doing this for herself. Monique is playing a guitar. It was a spur of the moment idea - this might actually be her backyard, somewhere in the South. Monique might be a song writer in Nashville trying to make a name. She would like to be famous. She could also be a pan-handler for all we know!
This might be taking place in the 1950's or '60's or it could be more modern. After finishing playing she'll write another song. After practicing she's going to her day job. Then she'll go back and write more lyrics.
We assume she has a family but they live somewhere else, in another part of the country. Monique moved to be a singer. She's feeling hopeful but somber and reflective, too.
