In 1982, musicologist Franco Fabbri proposed a definition that would become the bedrock of modern musicology, describing a musical genre not as a fixed box but as a set of musical events governed by socially accepted rules. This concept transformed how we understand the boundary between a song and a culture, suggesting that the very existence of a genre relies on the collective agreement of its listeners and creators. Before this theoretical shift, music was often categorized simply by its sound or origin, but Fabbri's framework revealed that genre is a dynamic social contract. It explains why a piece of music can be classified as jazz in one context and popular music in another, depending on the rules the community applies to it. The definition of genre has since graduated from being a mere subset of popular music studies to becoming an almost ubiquitous framework for evaluating all musical research objects, according to Timothy Laurie. This shift in perspective allows us to see that the distinction between art and popular music is not inherent in the notes themselves, but in the distribution strategies and consumption patterns that surround them. The proliferation of over 1,200 definable subgenres in the 20th century proves that these categories are not static; they evolve, fracture, and merge as society changes. The very act of classifying music is an attempt to impose order on a chaotic artistic landscape, yet the artistic nature of music ensures that these classifications remain subjective and often controversial. When a new style emerges, it is frequently lumped into existing categories, creating a genealogy of musical genres that can be expressed in written charts. This genealogy is not just a list of names but a map of cultural evolution, showing how new styles appear under the influence of pre-existing genres while simultaneously challenging their boundaries. The complexity of this system is further highlighted by the work of Glenn McDonald, who created an algorithmically generated scatter-plot of the musical genre-space based on data tracked for 5,315 genre-shaped distinctions. This data-driven approach attempts to quantify the unquantifiable, mapping the relationships between genres like Every Noise at Once, revealing the hidden connections that human listeners might miss. The result is a spectrum of genres that is constantly shifting, proving that the definition of a genre is always in flux, dependent on the social and technological context of the moment.
The Written Word and the Oral Tradition
The history of Western music is defined by a fundamental tension between the written word and the oral tradition, a divide that has shaped the very identity of art music for centuries. In the Western practice, art music is considered primarily a written musical tradition, preserved in some form of music notation rather than being transmitted orally, by rote, or in recordings. This reliance on notation means that the identity of a work is usually defined by the notated version rather than by a particular performance, and is primarily associated with the composer rather than the performer. The standard forms of music notation evolved in Europe, beginning well before the Renaissance and reaching its maturity in the Romantic period, creating a system where the composer's intent is fixed on the page. This stands in stark contrast to folk music, which is classified as the music that is orally passed from one generation to another, where the artist is often unknown and there are several versions of the same song. The transmission of folk music occurs through singing, listening, and dancing, allowing culture to transmit the styles and the context in which it was developed. This oral tradition maintains rich evidence about the period of history when the songs were created and the social class in which they developed. While English folk music has developed since the medieval period and has been transmitted from that time until today, Turkish folk music relates to all the civilizations that once passed through Turkey, thereby being a world reference since the east-west tensions during the Early Modern Period. The distinction between these two modes of transmission is so profound that musicologist Philip Tagg developed an axiomatic triangle consisting of folk, art, and popular musics to distinguish them. Tagg maintains that popular music differs from art music through its mass distribution strategy as well as its non-written distribution modes, which produces distinct production and consumption patterns between these categories. This difference is not merely technical but sociological, affecting how music is created, consumed, and remembered. The advent of sound recording technologies in the 20th century created a third branch of music, what Vincenzo Caporaletti calls Audiotactile music, where the process of production and transmission is pivoted around sound recording technologies. This includes genres like jazz, pop, rock, and rap, which are created by means of the audiotactile matrix in which the formative medium is the Audiotactile Principle. The shift from the visual matrix of written music to the audiotactile matrix of recorded music fundamentally changed the relationship between the artist and the audience, allowing for a new kind of intimacy and immediacy that was impossible in the era of notation alone. The evolution of these genres reflects the changing nature of human communication, moving from the static page to the dynamic recording, and finally to the digital stream that defines the modern listening experience.
