"Blast Away! -Gummi Ship III-" is approximately one minute and fifty-one seconds long, has a time signature of 4/4, and plays at a tempo of 140 beats per minute. The instrumentation includes: a complete strings section- violin, viola, cello, and string bass, flute, oboe, trumpet, French horn, trombone, tuba, strings section, orchestral bells, snare drum, crash cymbals, and timpani.
Compared to "Blast Away! -Gummi Ship I-" and "Blast Away! -Gummi Ship II-", the third variation of the "Blast Away!" theme is much darker in tone. The once cheerful, major key shared in the first and second versions are no more, as the melody in this version is played in a minor key. Although more ominous and intense in nature, this tone is befitting as this is the final Gummi Ship route in the game.
