The music for "Type-0" was composed by Takeharu Ishimoto. He had previously composed the music for "Before Crisis", "Crisis Core" and "The World Ends with You". Ishimoto gave the music a dark and heavy feel, describing the themes as "war, life, and death". He used less rock elements than in his previous games to promote a feeling of immersion. One of his primary instruments was the guitar, which Ishimoto played himself during recording sessions. Although the title was for the PSP, the team did not want to hold back despite hardware limitations, recording a quantity of tracks unusual for a spin-off "Final Fantasy" title. Wherever possible, the recording was done live. The orchestral and choral elements were performed by the Sydney Symphony Orchestra and the Cantillation chamber choir, and the recording and mixing of these tracks was done at the Sydney Opera House. Recording for other tracks was done at Ishimoto's studio in Japan. After recording, Ishimoto combined the orchestral and choral elements, and rearranged the main leitmotifs to create more variety in the score. Arrangements for the orchestral tunes were done by Kentaro Sato, while arrangements for other tracks were done by Rieko Mikoshiba.
