AI is coming for music, too

... By transforming random noise into coherent patterns, diffusion models can generate new images, videos, or speech, guided by text prompts or other input data. The best ones can create outputs indistinguishable from the work of people, as well as bizarre, surreal results that feel distinctly nonhuman.  ...

For years, diffusion models have stirred debate in the visual-art world about whether what they produce reflects true creation or mere replication. Now this debate has come for music, an art form that is deeply embedded in our experiences, memories, and social lives. Music models can now create songs capable of eliciting real emotional responses, presenting a stark example of how difficult it’s becoming to define authorship and originality in the age of AI. ...

Is creativity, whether in artificial neural networks or biological ones, merely the result of vast statistical learning and drawn connections, with a sprinkling of randomness? If so, then authorship is a slippery concept. If not—if there is some distinctly human element to creativity—what is it? ...

Studies have shown that highly creative people may perceive very semantically distinct concepts as close together. Artists have been found to generate word associations across greater distances than non-artists. Other research has supported the idea that creative people have “leaky” attention—that is, they often notice information that might not be particularly relevant to their immediate task. ...

Musical images

The approach works much the same way for music. A diffusion model does not “compose” a song the way a band might, starting with piano chords and adding vocals and drums. Instead, all the elements are generated at once. The process hinges on the fact that the many complexities of a song can be depicted visually in a single waveform, representing the amplitude of a sound wave plotted against time.  ...

The results of Udio and Suno so far suggest there’s a sizable audience of people who may not care whether the music they listen to is made by humans or machines. Suno has artist pages for creators, some with large followings, who generate songs entirely with AI, often accompanied by AI-generated images of the artist. These creators are not musicians in the conventional sense but skilled prompters, creating work that can’t be attributed to a single composer or singer. In this emerging space, our normal definitions of authorship—and our lines between creation and replication—all but dissolve. ...
