Kingdom Hearts [SEP] Music
The music for the series has been primarily composed by Yoko Shimomura. Kaoru Wada works as the arranger for orchestral music, including orchestral renditions of the main vocal themes and the ending themes. The orchestral music was performed by the New Japan Philharmonic Orchestra and the Tokyo Philharmonic Orchestra. Soundtracks were released for the first and third installments following the release of their respective games. A compilation soundtrack was later released that included soundtracks for the entire series, including reworked tracks for the re-released "Kingdom Hearts Re:Chain of Memories". While the themes for some of the Disney-based worlds are taken directly from their Disney film counterparts, most of them are given entirely original musical scores.
