Writing a dissertation on music theory and genre evolution offers a rich landscape for exploring the technicalities of music composition, as well as the social and cultural shifts that shape musical genres over time. This kind of study delves into the complexities of music theory—such as harmony, melody, rhythm, and form—while examining how these elements evolve across genres like classical, jazz, rock, and electronic music. 

1. Define Your Research Scope: Theory, Evolution, or Both?

Before diving in, decide on the primary focus of your dissertation. Music theory and genre evolution are vast topics, so narrowing down your research question is essential. Here are some examples of how to frame your focus:

Theory-Centric: How has the use of harmony and dissonance evolved in jazz from its roots to contemporary forms?

Evolution-Centric: How did electronic music evolve from the analog synths of the 1970s to today’s digital production techniques?

Combined Focus: How has rock music’s theoretical structure changed as it has evolved from blues influences to subgenres like punk and alternative?

Clearly defining the scope of your research will help you stay on track and give your dissertation a solid foundation.

2. Start with a Historical Overview of Your Chosen Genre

A good dissertation on genre evolution begins by tracing the roots and historical context of the genre. Research how cultural, social, and technological factors influenced the genre’s inception and its evolution over time. For example, the history of jazz can’t be separated from the African American experience, just as electronic music’s rise is closely tied to advances in technology.

Consider these points as you explore genre history:

Origins: What were the genre’s earliest influences, and how did it take shape?

Key transitions: Identify pivotal points in the genre’s history, such as the British Invasion in rock music or the digital revolution in electronic music.

Subgenres: Examine how different subgenres emerged, each with its own stylistic and theoretical nuances.

Laying this groundwork sets up a rich context for analyzing theoretical changes and gives readers a thorough understanding of the genre’s evolution.

3. Dive Deep into Music Theory

The music theory component is where you get to dissect and analyze the technical elements of the genre. Each genre uses specific structures, scales, harmonic progressions, and rhythms that set it apart. Whether it’s jazz’s improvisational freedom, classical music’s counterpoint, or the minimalist loops of electronic music, understanding these elements is key to any study on music theory.

To effectively analyze music theory in your dissertation, focus on these elements:

Harmony and Melody: How does the genre use scales, chords, and melodic progressions? For example, jazz frequently employs complex chord extensions and substitutions.

Rhythm and Meter: Does the genre use syncopation, polyrhythms, or unconventional time signatures? Rock and blues, for instance, often rely on straightforward 4/4 time, while jazz and world music use varied meters.

Form and Structure: How are songs or compositions structured? Many pop songs follow a verse-chorus structure, while classical symphonies might follow sonata form.

By analyzing these theoretical aspects, you can reveal how each component contributes to the genre’s signature sound and texture.

4. Examine Key Examples and Influential Works

Your dissertation can be strengthened by analyzing specific, influential works that exemplify changes in theory and style within the genre. Select pieces that capture the essence of theoretical shifts or are representative of genre-defining moments. For instance:

Classical to Romantic: Beethoven’s transition from the classical to the romantic period can highlight changes in emotional expression and harmonic experimentation.

Early Jazz to Bebop: The evolution from Louis Armstrong’s swing to Charlie Parker’s bebop demonstrates increasing harmonic complexity and rhythmic speed.

Analog to Digital in Electronic Music: Compare early analog works by Kraftwerk with modern digital productions to show technological and stylistic changes.

By focusing on a few well-chosen examples, you can illustrate how theoretical concepts and genre elements have evolved over time in a tangible, relatable way.

5. Analyze the Cultural and Social Impacts on Genre Evolution

Genres evolve not only from within but also through the influence of external cultural and social changes. Explore how shifts in society, politics, and technology have left their mark on your chosen genre. For example:

Jazz and Civil Rights: The development of jazz is inextricably linked to African American history and the civil rights movement, with artists using their music to express social and political messages.

Rock and Youth Rebellion: Rock music has long been associated with countercultural movements, from the anti-establishment vibes of the 1960s to punk’s DIY ethos in the 1970s.

Hip-Hop and Urban Culture: Hip-hop’s rise reflects the experiences of urban communities, with lyrics often addressing social injustice, poverty, and resilience.

Examining these social influences offers a more holistic view of genre evolution and illustrates how music reflects the values and struggles of its time.

6. Incorporate Comparative Analysis Across Genres

Genre evolution often involves cross-genre influence and fusion. Explore how one genre borrows elements from others, leading to new sounds and hybrid forms. For instance, jazz has influenced countless genres, from rock to hip-hop, and continues to be a touchstone in modern music.

Here are some ways to approach comparative analysis:

Fusion Genres: Look at genres like jazz fusion or folk-rock, which combine elements from multiple sources.

Borrowed Theory and Techniques: How has the introduction of jazz improvisation influenced classical compositions? How has the use of sampling in hip-hop transformed music production techniques in pop?

Genre Hybrids: Examine how artists like Beck or genre-blending bands like Radiohead pull from multiple genres to create unique sounds.

This cross-genre perspective can offer fresh insights and add layers of complexity to your analysis.

7. Utilize Digital Tools for Analysis

Analyzing music theory and genre evolution requires handling complex data, multimedia sources, and extensive notes. Digital tools can streamline your research process, helping you manage everything from academic sources to multimedia.

Consider these tools to enhance your research:

Music notation software: Tools like MuseScore or Sibelius are useful for transcribing and analyzing music.

Digital libraries: JSTOR, Project MUSE, and other academic databases have extensive resources on musicology and theory.

Audio editing software: Programs like Audacity or Ableton Live allow for close analysis of audio samples and production techniques.

Using digital resources ensures you can organize your findings and analyze complex theoretical points with precision.

8. Conclude with Reflections on Modern Genre Evolution

A strong dissertation on music theory and genre evolution should not only look to the past but also consider the genre’s potential future. Music continues to evolve in response to changing social, cultural, and technological landscapes. In your conclusion, speculate on how the genre might continue to change and what theoretical developments could arise.

Some closing reflections might include:

Technological advancements: How might AI or new instruments change the way genres are produced or perceived?

Cultural shifts: How could current social movements influence music? Will genres like hip-hop continue to be a platform for social commentary?

Globalization and genre fusion: How will increased cross-cultural exposure shape new genre hybrids?
