Tomoya Ohtani on Sonic Lost World Original Soundtrack:

Title Screen

I composed the main theme Wonder World’s intro part, which seems to make us look forward to the playing that starts from here and the story’s development, with the prerequisite of it being used in the title screen. The piano and celesta which continue after the intro, such silent and mysterious starting is great as well, isn’t it? It’s because plenty of energetic music will come to appear after this. (Laughs)
