Breaking the Sound Barrier: Exploring the World of Contemporary Classical Music

Introduction to Contemporary Classical Music

Contemporary classical music, also known as “new music,” is an art form that has emerged from the Western art music tradition. This genre of music encompasses a diverse range of styles and compositions, ranging from post-tonal music to electronic and experimental music.

In this article, we will delve into the development of contemporary classical music, the role of modernism and serialism, and the main players who shaped this genre.

Development of Contemporary Classical Music

Contemporary classical music emerged in the 20th century, following the collapse of traditional tonality. In the years that followed, composers began experimenting with new musical styles, breaking away from the traditional harmonic structures and moving towards a more dissonant and atonal sound.

One of the key developments in the evolution of contemporary classical music was the incorporation of electronic instruments and technology. This allowed composers to create new sounds, manipulate existing sounds, and layer different elements to create complex musical compositions.

This also led to a blurring of genre lines, as contemporary classical music began to incorporate elements of jazz, rock, and other popular music styles.

Serialism and the Continuation of Modernism

Modernism, which emerged in the late 19th and early 20th centuries, was a movement that celebrated novelty and experimentation in art, literature, and music. In the realm of music, modernism was characterized by a break away from traditional tonality and a focus on dissonance, chromaticism, and complex rhythmic structures.

At the forefront of modernism was a composer by the name of Arnold Schoenberg. Schoenberg pioneered a new compositional technique known as serialism, which involved organizing musical elements according to predetermined patterns.

This allowed for greater control over the composition and created a new kind of musical language. Post-war serialism, also known as high modernism, emerged in the years following World War II.

It was characterized by an even greater emphasis on predetermined patterns, as well as a focus on complexity, intellectual rigor, and experimentation. Key figures in the post-war serialism movement include Milton Babbitt, Pierre Boulez, and Karlheinz Stockhausen.


Contemporary classical music is an art form that continues to evolve and push the boundaries of traditional tonality and musical structure. From the incorporation of electronic instruments to the development of serialist compositional techniques, this genre of music has seen a wide range of innovations over the years.

As the genre continues to evolve, it will be interesting to see where it goes next and how it continues to shape the future of classical music.

3) Experimental Music

Experimental music is a genre of music that encompasses various sub-genres, such as avant-garde, free jazz, and noise. What sets experimental music apart from other genres is its unconventional approach to music-making.

Instead of adhering to traditional musical structures, experimental music seeks to push the boundaries of sound and composition. The roots of experimental music can be traced back to the mid-20th century, when John Cage emerged as one of its most influential figures.

Aleatoric music, also known as chance music, is a form of experimental music that involves the incorporation of chance elements in the composition process. Rather than pre-determining all musical elements, composers include elements that allow for fluctuations in the music.

One example of aleatoric music is the use of graphic scores, where the composition is laid out in a visual format that the performers interpret. Music concrete is another form of experimental music that involves the manipulation of recorded sounds.

In music concrete, composers take existing sounds and manipulate them through various means to create musique concrete compositions.

4) Computer Music and Spectralism

One of the most significant developments in experimental music in recent years has been the incorporation of computers in music composition. Computers have opened up new possibilities for composers, allowing them to create complex sounds and manipulate them with ease.

At the heart of computer music is the algorithm, a set of mathematical instructions that generate patterns and sequences. One of the key features of computer music is the use of synthesized sounds.

Synthesized sounds are created through digital manipulation of sound waves and can be manipulated in a wide range of ways. Digital manipulation allows composers to tweak sounds in ways that would not be possible using traditional instruments.

Spectralism is another sub-genre of experimental music that emerged in the late 20th century. Spectralism focuses on the analysis of sound spectra, which refers to the acoustic properties of sound.

Spectral composers are interested in the harmonic series, which is a series of frequencies that are related to one another by whole number ratios. Microtones, which are intervals smaller than those found in traditional Western music, are also explored in spectralism.

In spectralism, composers focus on the timbral qualities of sound rather than traditional tonality. The goal of the composer is to create complex sounds and textures using spectral analysis.

Composers use various techniques, such as filtering, modulation, and granulation, to create these textures.


Experimental music is a genre of music that has been defined by its unconventional approach to composition and sound. From aleatoric music to musique concrete, experimental music has shown the potential of chance elements and unconventional sound sources.

The use of computers in music composition has further expanded the genre, providing composers with new tools for sound manipulation and generation. Spectralism has brought attention to the analysis of sound spectra, offering a new way of thinking about the composition of sound.

Experimental music continues to push the boundaries of sound and music creation, and its influence can be seen in various forms of music today.

5) Minimalism

Minimalism is a genre of music that emerged in the 1960s and 70s. It is characterized by a stripped-down sound that focuses on repeating fragments of music, creating hypnotic tapestries of sound.

The music often features a limited number of musical elements, such as a simple harmonic structure or repetitive melody. One of the most famous minimalists is Steve Reich, who created compositions that featured repetitive rhythms.

His compositions often used a technique called “phasing,” where two or more rhythmic patterns start in unison and gradually move out of phase with each other. Post-minimalism emerged in the 1980s and was characterized by a move towards more complex structures.

Composers began incorporating elements of non-Western music, such as gamelan and African drumming. They also began drawing inspiration from popular music styles, such as rock and jazz.

6) Current Composers of Contemporary Classical Music

Contemporary classical music is a broad category that encompasses many different styles and genres. Some composers draw inspiration from classical music traditions, while others incorporate elements of popular music, jazz, or experimental music.

One notable contemporary composer is Arvo Prt, an Estonian composer known for his minimalist compositions. His music often features sparse, slow-moving harmonies that create a meditative atmosphere.

Rhys Chatham is another contemporary composer known for his minimalist compositions. He is known for his use of large ensembles, often featuring multiple electric guitars.

Anna Meredith is a British composer who draws on elements of pop and electronic music in her compositions. Her music often features driving rhythms and catchy hooks.

Harrison Birtwistle is an English composer known for his complex, experimental compositions. His music often features unconventional instrumentation and complex rhythms.

Steve Reich continues to be one of the most influential composers in the contemporary classical music scene. His minimalist compositions have inspired countless other composers and continue to be performed around the world.

These composers represent just a small sampling of the many talented individuals currently working in contemporary classical music. The genre continues to evolve and develop, reflecting the unique artistic sensibilities of each generation.

As new technologies and cultural influences emerge, it will be exciting to see how contemporary classical music continues to grow and change in the years to come. In conclusion, contemporary classical music is a vibrant and constantly evolving genre of music that encompasses a wide range of styles and influences, from minimalism and post-minimalism to spectralism and experimental music.

Emerging from the Western art music tradition, contemporary classical music continues to push the boundaries of sound and composition, drawing inspiration from non-Western music and popular music. Notable contemporary composers, such as Arvo Prt, Rhys Chatham, Anna Meredith, Harrison Birtwistle, and Steve Reich, are continually shaping the genre and expanding its horizons.

The importance of contemporary classical music lies in its ability to offer new perspectives on sound and composition, crossing boundaries and blending genres in exciting and innovative ways.
