As with all analysis, we'll break the song down into four parts - the song itself, the arrangement, the sound and performance.
The Song - "Firework" is a more or less traditional pop song in that it has a common structure found in most hits - short intro, verse, B-section, chorus, chorus, verse, B-section, chorus, chorus, bridge, chorus, chorus, outro. The form looks like this:
A, A, B, C, C, A, B, C, C, D, C, C, C.
That doesn't mean it's boring though. The song builds nicely and takes us through a couple of peaks, thanks to the song's built-in dynamics. It even has an ending, which is unusual for a pop song.
The Arrangement - The arrangement is state-of-the-art. The intro and first verse are very sparse, with the strings entering at the first B-section and continue to build to a crescendo through the 1st chorus. The chorus repeats with additional movement from the entrance of the bass.
The Sound - Once again, here's an example of how the sound of pop records has returned to the 80's/90's in that everything except has some depth to it. Katy has what sounds like a timed triplet delay on her voice that triggers the reverb, so there's depth and spaciousness without washing out. The same is true on the rest of the track in that there's some space around each instrument except for the bass and drums, which are dry and in your face.
The Performance - It's easy to think of Katy Perry as a lightweight because of her celebrity and exposure, but the girl has some pipes and this song proves it. She really sells the song and pulls you in. Plus, she sings harmony vocals very well with herself, which all singers can't do.

The first half of the second verse drops down to just 8th notes on the keyboards plus the drum pattern, but changes with the entrance of the bass into the second half - a very nice arrangement touch.
Some other things I especially liked is the line in between the repeat of the 2nd chorus, the harmony vocals on the repeat, and the background vocal answers in the outro. Also, listen to how the vocal melody subtly changes on the 2nd and 3rd choruses.
I always preach about dynamics as the key to excitement, either live or on a record, and this song is an excellent example of how it's done.
