a heavy chugging metal riff with pentatonic licks

K: Emin T: 130 TS: 4/4 INST: ElectricGuitarRhythm, ElectricGuitarLead, Bass, Drums Mood: aggressive, dark, driving, raw, ominous Structure: Riff-driven Verse–Chorus–Bridge (short intro riff → verse riff → chorus hook → bridge/solo → reprise) Summary: This description points to a mid‑tempo heavy metal groove built on palm‑muted, chugging low‑string power chords with lead lines drawn from the minor pentatonic scale. Expect high‑gain, tight‑sounding rhythm guitar (often low‑tuned or Drop D/Drop C for extra weight), a compressed distorted bass that locks with the kick and double‑kick drum patterns, and aggressive drums emphasizing snare on 2/4 with syncopated chug accompaniment and occasional blast/double‑bass flourishes. Arrange around a strong repeating riff for verses, a more open/power‑chord chorus for contrast, and a bridge/solo section featuring pentatonic licks and bends.
