The Symphony of Sorcery is a world composed of the dreams of the Mysterious Tower's past. New to the familiar tower are Mickey's songbooks, which serve as portals to three separate locations.

For Sora, Mickey summons a pink songbook based on ''{{w|Symphony No. 6 (Beethoven)|The Pastoral Symphony}}''. It leads to the {{nihongo|'''{{a|Cloudwalk}}'''|雲路|Kumoji}}, an expanse of clouds and rocky pillars connected by rainbows, beneath a brilliant blue sky. The Cloudwalk connects to a forested {{nihongo|'''{{a|Glen}}'''|峡谷|Kyōkoku|lit. "Canyon"}} filled with twisters and stormclouds, which itself ends at the stormy {{nihongo|'''{{a|Fields}}'''|平原|Heigen}}, a rainbow-colored field dotted with pavilions and the hiding place of the first Sound Idea.

For Riku, Mickey summons a blue songbook based on the ''{{w|The Nutcracker|Nutcracker Suite}}'', where everything is larger-than-life. The songbook opens up on the {{nihongo|'''{{a|Moonlight Wood}}'''|月光の森|Gekkō no Mori}}, a patch of flowers in the midst of night. Across a shining lake lies the {{nihongo|'''{{a|Golden Wood}}'''|金色の森|Kiniro no Mori}}, where the leaves themselves sprinkle pieces of [[Munny]]. At the top of that forest is a path to the wintry {{nihongo|'''{{a|Snowgleam Wood}}'''|雪明りの森|Yukiakari no Mori}}, a frozen landscape containing icy slides, floating snowflakes, chilly ponds, and the second Sound Idea. However, once Riku retrieves the Sound Idea, [[Young Xehanort]] appears and casts him into the '''{{a|Bald Mountain}}''', lair of the demon [[Chernabog]].<!--What is the source for this room name?{{fact}}-->

The final red songbook, based on ''{{w|The Sorcerer's Apprentice}}'', contains a simple {{nihongo|'''{{a|Precipice}}'''|絶壁|Zeppeki}} above the sea where the [[Spellican]] lurks. When Sora arrives, he chases the Nightmare onto a starry road flowing through the sky, which also contains a miniature arena filled with multicolored asteroids and a stellar river.

The Symphony of Sorcery's Reality Shift, [[Melody Catcher]], is vital for exploring the realm of the songbooks. It allows Sora to summon new clouds and rainbows in the Cloudwalk, calm the twisters in the Glen, and sweep away the stormy night in the Fields. Conversely, Riku uses the technique to open flower buds and part weeds in the Moonlight Wood, sprout a bower of leaves in the Golden Wood, and summon giant snowflakes in the Snowgleam Wood.<!--which songs? are they per songbook or room? In turn, each room provides a new melody to match the room's theme.-->

Following the battle, Riku finds himself back in Yen Sid's tower just as Sora returns to the tower in his version of the world. Their sides' respective Mickeys conclude that one Sound Idea is not enough to rid the darkness from the possessed book. Having faith in each other, Sora's and Riku's Sound Ideas appear in the other's world. With the Sounds Ideas combined, it created [[Dearly Beloved|a powerful harmony]] that clears the flooding water from the room and frees Mickey from the darkness on Riku's side. When Mickey inquires about what had happened, a grateful Riku guesses that Sora helped him. Mickey comments that hearing Sora's name makes him want to smile, and Riku starts telling him about Sora and how he can always "find the brightest part of anything, and pull off miracles like there's nothing to it". Mickey expresses his delight that Sora's heart and Riku's are always in tune and thinks it is thanks to Riku that Sora is who he is. Mickey voices his hope that he will also be part of a team someday, and with a smile and a handshake, Riku assures him that he will. Afterwards, the [[Keyhole]] appears and Riku unlocks it before continuing on his journey.
