Part of Me (Katy Perry song) [SEP] Composition and lyrical interpretation
"Part of Me" is a dance-pop and power pop song set to a house beat. It is composed in the key of D minor and set in a 4/4 time signature at a tempo of 130 beats per minute. The melody spans the tonal range of D to D, while the music follows the chord progression of Dm–F–Bb-C. Production was done by Perry's frequent collaborator, Dr. Luke. The song begins with Perry's somber and emotional delivery of the line, "Days like this I want to drive away/ Pack my bags and watch your shadow fade." At the bridge, the beat amplifies and Perry's lyrics become more aggressive as she commands "Now Look at Me!", signalling to her ex that she is still strong, regardless of what he tries to do to bring her down.
