All of the chords used in the piece of music are diatonic and chromatic, with no diatonic and chromatic alterations; it has been said that this "adds to the directness of the music". The main melody is scored for a piano, which has been described as having a "pub sing-a-long feel" to it. The tune is also doubled by a whistle, and there are two rhythmic permeations, a dotted quarter note-eighth note moving the music forward, and a two-quaver hand-clap on the fourth beat of every other bar.
