Star Ship contains a remix of the harmony from Theme of Samus performed by strings, with a lot of emphasis on a new choir melody. It also features percussion instruments commonly heard throughout the Echoes soundtrack.
Star Ship's arrangement is slightly different across all three games. The Corruption version is nearly identical to the Echoes version, but it is shorter in length and the strings sound louder and more tense. In Samus Returns, the strings now sound even darker and more aggressive than before, fitting the nature of Samus's mission to exterminate an entire species.
