Page:Musical Structure as Narrative in Rock 13.png

Encarnacao the miniature quest narrative of each iteration of the strophe contributes to a larger quest narrative, with density, register, dynamics and timbre articulating a sense of goal and return. While it is important to acknowledge that quest narrative can emerge through the timbral and textural trajectory of the sound-mass (and, in fact, this often happens iin tandem with the structural process of quest narrative form), the omission or obfuscation of verse-chorus-bridge or strophic structures in immersive forms leads us to experience rock recordings in an entirely different way

Conclusion
All of the examples here that avoid or obscure the conventional structural markers that result in the quest narrative shape downplay harmonic contrast in favour of timbral contrast or an aesthetic that embraces minimal musical means or material. These structures are articulated either through repetition or a drone aesthetic (single-cell and immersive forms) or a multiplicity of sections that explodes conventional rock song form (labyrinth forms). At the risk of drawing the sorts of parallels to classical music that Walser and others have cautioned against, it is as if rock music might be said to be going through a process of exploration not dissimilar to that embarked upon by Western art music composers of the period 1920-1970. As Lochhead asserts, "The twentieth century has witnessed the erosion of the belief that the Aristotelian principles of aesthetics are absolute. Composers have compositionally explored alternate means of temporal organization' (1992: 134). These include, but are not limited to: Edgard Varèse, who initiated a move towards timbre and texture as the chief articulators of structure; the pioneers of musique concrète and electronic composition such as Pierre Henry, Pierre Shaeffer, John Cage and Karlheinz Stockhausen, where harmony and rhythm are often subordinated to the phenomena of sound-as-itself, and minimalists La Monte Young, Steve Reich, Terry Riley and Philip Glass. I am not suggesting that rock music is 'behind, and 'catching up to' art music, or that art music is the sole bastion of innovation. Pop and rock have always had their own possibilities and effects. It is also apparent that in rock music, structures have always been articulated through sound itself as much as by harmonic or rhythmic organisation. ___________________
