A zaftig woman in a tube top and jeans dancing outdoors, with a guitarist behind her.
A woman is dancing to a mans guitar playing.
The woman may be dancing to her own music, the man doesn't have to play his guitar if there is other music.
A guitarist being behind a dancing woman does not necessarily indicate that she is dancing to music the guitarist is playing or that the guitarist is even playing.
We do not know if she's listening to a mans guitar or a woman's.
