A fast heavy metal riff with chugging and pentatonic licks

K: Em T: 180 TS: 4/4 INST: Distorted Electric Guitar, Bass Guitar, Drums Mood: Aggressive, Energetic, Powerful, Driving Structure: Too limited to infer a full song structure; this riff is likely a foundational element (e.g., a main verse or pre-chorus riff) within a larger, typical heavy metal song structure (like Verse-Chorus-Bridge). This description evokes the core sound of classic and modern heavy metal. The "fast" tempo and "chugging" immediately suggest a high-energy, percussive guitar riff driven by palm-muted power chords. "Pentatonic licks" indicate that while the rhythm is heavy, there will also be melodic or soloistic elements, likely within the minor pentatonic scale, adding a bluesy yet aggressive edge common in metal. The overall feel is one of intense power and rhythmic propulsion, characteristic of the genre.
