Frampton penned this song when she was hanging out with former Evanescence member David Hodges (Kelly Clarkson, Daughtry) and John Mayer's guitar player Dave Harris. She recalled to Alternative Press: "Dave (Hodges) started playing a tune and I said, 'Wow, I love that beginning. Let's build on that song. It's great!' And he laughed and said, 'I was just messing around. That's a Bob Dylan song I was playing.' Of course I felt rather stupid, but then we just started jamming folk songs and 'Trapeze' came out."
Frampton wrote the song's lyrics about a friend's disclosure of a horrific childhood that he had kept hidden until she had known him for four years. She told Alternative Press: "It was odd because, lots of people with their dark pasts tend to dwell on them and sometimes victimize themselves, leaning on their crutches as an excuse not to press forward. My friend, on the other hand, lived as if nothing had ever happened. When he told me of his past I was shocked. It's amazing how some people can overcome hardships and move forward, becoming their own person."
