Chrono Trigger Orchestra Extra Soundtrack is an album of orchestral arrangements of Chrono Trigger songs, arranged by Natsumi Kameoka. Published by Square Enix on November 20, 2008 exclusively as a pre-order bonus of the Nintendo DS port of Chrono Trigger, this soundtrack consists of two tracks, "Chrono Trigger ~Orchestra Version~" and "Chrono Trigger Medley ~Orchestra Version~", the latter spanning the songs "A Premonition", "Guardia's Millennial Fair", "Yearnings of the Wind", "Frog's Theme", "Battle with Magus", "Epilogue ~To Good Friends~", and "To Far Away Times". Mitsuda expressed difficulty in selecting the songs for the orchestral medley, eventually picking a song from each era and certain character themes. While both tracks involve a full orchestra, "Chrono Trigger" is more heavily horn-based, while "Medley" relies more on stringed instruments. The CD itself came in a single sleeve with a short note from primary composer Yasunori Mitsuda. The album as a whole has a length of 6:18, with "Chrono Trigger" lasting 2:07 and "Medley" having a length of 4:11.
