How To Understand the Subgenres of Heavy Metal

Heavy metal, often simply called metal, is one of the most diverse and influential genres of music. Since its inception in the late 1960s and early 1970s, heavy metal has evolved significantly, branching out into numerous subgenres, each offering its own distinct sound, aesthetic, and cultural significance. Understanding these subgenres not only enhances one's appreciation of heavy metal as a genre, but also provides insight into the cultural, social, and artistic developments within the genre over time.

In this article, we will explore the various subgenres of heavy metal, diving deep into their histories, characteristics, and key bands that helped define and shape them. From the classical influences of early metal to the extreme elements found in modern subgenres, we will look at what sets each subgenre apart and how these different styles interact with one another.

The Roots of Heavy Metal

Before diving into the subgenres, it's important to understand the origins of heavy metal itself. The genre began to take shape in the late 1960s and early 1970s, largely influenced by the aggressive sounds of hard rock and the blues-based rock of bands like Led Zeppelin, Black Sabbath, and Deep Purple.

The term "heavy metal" is often attributed to the 1968 Steppenwolf song "Born to be Wild," in which the lyrics mention the phrase "heavy metal thunder." However, it was Black Sabbath's self-titled 1970 album that truly laid the foundation for the genre, with its slower tempos, distorted guitars, and dark, ominous atmosphere.

As the 1970s progressed, metal became more distinct from its rock predecessors, adopting characteristics that would later define its many subgenres. The combination of power chords, aggressive drumming, and virtuosic guitar solos formed the core of what we now know as heavy metal. But soon, bands began to experiment with these elements, giving rise to the many subgenres of metal we recognize today.

Traditional Heavy Metal

Characteristics:

Traditional heavy metal, or classic metal, refers to the early sound of heavy metal as pioneered by bands like Black Sabbath, Judas Priest, and Iron Maiden. These bands introduced powerful, mid-tempo rhythms, screeching vocals, and elaborate guitar solos that became staples of the genre.

The musical style in traditional heavy metal is characterized by:

• Powerful Guitar Riffs: Heavy, distorted, and often harmonized riffs set the tone for most songs.
• High-Pitched Vocals: Many early heavy metal singers, such as Rob Halford of Judas Priest, are known for their high-pitched screams and wails.
• Song Structure: Songs often feature verses, choruses, and guitar solos, with lyrics that frequently focus on rebellion, mythology, and fantasy.

Key Bands:

Traditional heavy metal remains a cornerstone of the genre, and bands from the '80s onwards continue to draw inspiration from this classic style.

Thrash Metal

Characteristics:

Emerging in the early 1980s, thrash metal was a faster, more aggressive evolution of traditional heavy metal. Influenced by the speed and aggression of punk rock, thrash metal is known for its fast tempos, intricate guitar work, and socially conscious lyrics. The genre features tightly-knit rhythms, often accompanied by rapid drumming and fast, palm-muted guitar riffs.

Death Metal

Characteristics:

Death metal emerged in the late 1980s and is known for its extreme intensity, both in terms of speed and heaviness. The genre features heavily distorted guitars, blast beat drumming, and guttural growling vocals. It's also characterized by its dark, violent, and often grotesque lyrical themes.

Key characteristics of death metal include:

• Growled Vocals: Unlike traditional heavy metal, death metal singers use guttural growls and low-pitched screams that are difficult to understand but add to the genre's brutal sound.

Death metal is one of the most extreme forms of metal, pushing the boundaries of aggression and technicality to their limits.

Black Metal

Characteristics:

Black metal, originating in the early 1990s in Norway, is known for its atmospheric, eerie sound, and dark themes. The genre incorporates fast tempos, tremolo-picked guitars, and shrieking, high-pitched vocals. Black metal also emphasizes a DIY ethos and often features an unpolished, raw production style.

Key characteristics of black metal include:

• Darkthrone: Known for their stripped-down, lo-fi production, Darkthrone is a foundational band in the Norwegian black metal scene.

Black metal has evolved over time, with some bands incorporating elements from other genres, but it remains one of the most extreme and controversial subgenres of heavy metal.

Power Metal

Characteristics:

Power metal emerged in the mid-1980s as a more melodic and uplifting form of heavy metal. Drawing influences from both traditional heavy metal and classical music, power metal is known for its fast tempos, soaring vocals, and epic, fantasy-based lyrics.

Power metal's emphasis on melody, speed, and fantasy themes makes it a highly energetic and optimistic subgenre in contrast to other, darker forms of metal.

Doom Metal

Characteristics:

Doom metal is characterized by its slow tempos, heavy riffs, and melancholic or apocalyptic lyrics. While doom metal shares some similarities with traditional heavy metal, it takes a much darker and slower approach, focusing on despair, death, and existential themes.
