Evolution of Music by Public Choice

Music evolves as composers, performers, and consumers favor some musical variants over others. To investigate the role of consumer selection, we constructed a Darwinian music engine consisting of a population of short audio loops that sexually reproduce and mutate. This population evolved for 2,513 generations under the selective influence of 6,931 consumers who rated the loops’ aesthetic qualities. We found that the loops quickly evolved into music attributable, in part, to the evolution of aesthetically pleasing chords and rhythms. Later, however, evolution slowed. Applying the Price equation, a general description of evolutionary processes, we found that this stasis was mostly attributable to a decrease in thefidelity of transmission. Our experiment shows how cultural dynamics can be explained in terms of competing evolutionary forces.



The evolution of music by public choice is a fascinating process that highlights the dynamic interplay between artists, the music industry, and audiences. It underscores how consumer preferences, cultural trends, and technological advancements drive changes in musical styles, genres, and the overall landscape of the music industry. This evolutionary process is not linear but rather a complex feedback loop where public choice influences the production of music, which in turn shapes future preferences and trends.

### Historical Overview

Historically, music evolved through cultural traditions, with folk songs and classical compositions reflecting the societal values, stories, and emotions of their times. However, the 20th century introduced significant changes with the advent of recording technology, radio, and television, which broadened the reach of music and allowed audiences to play an active role in its evolution.

### The Role of Recording Technology

The ability to record and distribute music transformed the industry, making music more accessible to a broader audience. This democratization meant that public choice began to have a more direct impact on the success and propagation of different musical styles. Genres that resonated with the public flourished, while others faded into obscurity, guided by sales, radio play, and later, streaming numbers.

### Influence of Radio and Television

Radio and television became powerful mediums for exposing audiences to new music. Artists and genres that received airplay reached wide audiences, influencing public tastes and preferences. Programs like “American Bandstand” and later, MTV, played pivotal roles in shaping the musical landscape by dictating which artists and genres gained popularity.

### The Internet and Digital Revolution

The advent of the internet and digital music platforms has arguably been the most significant factor in the evolution of music by public choice in recent decades. Platforms like YouTube, Spotify, and SoundCloud democratized music production and distribution, allowing independent artists to reach global audiences without the backing of major record labels. Social media and streaming data now provide immediate feedback on public preferences, influencing the music industry’s direction in real-time.

### The Feedback Loop

The relationship between music evolution and public choice is a feedback loop. Artists experiment with new sounds and concepts, influenced by existing cultural trends, technological possibilities, and their creative visions. The public’s reception of these innovations then determines which directions become mainstream or fall by the wayside. Over time, what was once avant-garde can become the new norm, only to be challenged by the next wave of musical evolution.

### Crowdsourcing and Collaborative Creation

In recent years, some artists have taken the concept of public choice in music evolution a step further by directly involving fans in the creative process through crowdsourcing. This approach can range from selecting singles and album artwork to suggestions for lyrics and melodies, making the evolution of music an even more collaborative process between artists and their audiences.

### Conclusion

The evolution of music by public choice reflects a complex interplay of cultural, technological, and economic factors. It highlights the power of audiences in shaping the musical landscape and underscores the fluid nature of musical tastes and trends. As technology continues to evolve and new platforms emerge, the ways in which public choice influences music will undoubtedly continue to expand and transform.
