I'm not entirely sure specifically what 'Beethoven Visual Novel' is about, but it could be an attempt to bring the world of Beethoven to a new audience through the medium of a visual novel. It may include historical events related to him, like his concerts, his patrons, and his contributions to the development of classical music. It could also incorporate elements of fantasy or alternate history, such as what if Beethoven had made different choices in his career or personal life. The visual aspect would likely be used to depict the settings, characters, and key moments in Beethoven's life in an engaging way.
Well, it might be a visual novel that focuses on the creative process of Beethoven. It could show how he composed his masterpieces, his struggles with deafness, and his relationships with other musicians and people in his life. It could also explore the impact of his music on different characters in the novel. For example, a character might find inspiration in his symphonies and change their life because of it. The visual novel might use Beethoven's actual music to enhance the atmosphere and mood of the story, making it a really immersive experience for the players.
