Final answer:
Computers can be used in composition to create multimodal works combining text, images, and sound, as well as CGI for films and digital art. They enable publication and sharing of non-digital works online, and consider accessibility by incorporating modes like text and audio descriptions.
Step-by-step explanation:
Computers serve as powerful tools in the realm of composition, pushing the boundaries beyond simple sound generation. In the creative processes, computers facilitate composition by offering a variety of modalities and technologies. For instance, 3D computer graphics and computer-generated animations allow creators to construct virtual environments with intricate detail, providing a new canvas for filmmakers and digital artists. Movies extensively utilize computer-generated imagery (CGI) to create mesmerizing visuals that would otherwise be impossible or impractical to capture with traditional methods.
Multimodal compositions are those that combine different modes of communication such as text, images, and audio. These compositions can take the form of websites, flyers, or even photo essays that employ various media to enhance the viewers's understanding and engagement. An example could be the use of impactful images alongside text to highlight environmental concerns, thus making the message much more potent.
Moreover, technology aids in publishing and sharing compositions. Non-digital works like live performances or physical art can be recorded or photographed and uploaded to digital platforms, merging traditional art forms with modern technology. Multimodal compositions also pay attention to accessibility through interaction constraints, ensuring content is consumable by as diverse an audience as possible, such as providing text and audio descriptions for individuals with visual impairments.
