Structure
The structure of He's A Pirate follows what happens on screen and is heard when one of the leading characters is first seen on screen. This means that the song is broken up into themes that will be revisited throughout the film. The structure is:

6-bar introduction
theme A
theme B
theme C
theme B repeated

Melody
Each of the themes feature the following identities:

all of the themes begin with an anacrusis
each melody is conjunct and is played within a narrow range
the music moves in a wave-like motion, ie. the melody will rise and fall in pitch

Instrumentation and timbre

These are some of the essential pieces of information needed when answering questions regarding these two elements of music:

the entire score is written for a large orchestra
each instrument plays marcato throughout
only the strings play in the introduction with accents to accompany the themes
there is a heavy use of cymbals and untuned percussion
the implementation of brass instruments allows the melody to sound heroic and proud
the music has a swaying feel with lots of energy
