Vertigo

Metal (often used to mean heavy metal in its broad, umbrella sense) is a loud, guitar-driven style of rock defined by high-gain distortion, emphatic and often martial rhythms, and a dense, powerful low end. It foregrounds riff-based songwriting, dramatic dynamics, virtuosic guitar solos, and commanding vocals that range from melodic wails to aggressive snarls and growls. Harmonically, metal favors minor modes, modal color (Aeolian, Phrygian), chromaticism, and tritone-inflected tension, while thematically it explores power, mythology, the occult, social critique, fantasy, and existential subjects. While adjacent to hard rock, metal typically pushes amplification, distortion, precision, and thematic intensity further, forming a foundation for many specialized subgenres.

Psychedelic rock is a style of rock music that seeks to evoke, simulate, and expand altered states of consciousness through sound. It typically features timbral experimentation (fuzz, wah, tape delay, phasing), drones, modal or raga-influenced harmony, extended improvisation, studio-as-instrument production, and surreal, mystical, or mind-expanding lyrics. Emerging from mid-1960s counterculture, it fused garage-band energy with folk, blues, and non-Western musical ideas—especially Indian classical ragas—while embracing new studio technologies and concert light shows. Both a live and a studio art, psychedelic rock ranges from jangly, kaleidoscopic pop to heavy, hypnotic jams and cosmic soundscapes.

Rock is a broad family of popular music centered on amplified instruments, a strong backbeat, and song forms that foreground riffs, choruses, and anthemic hooks. Emerging from mid‑20th‑century American styles like rhythm & blues, country, and gospel-inflected rock and roll, rock quickly expanded in scope—absorbing folk, blues, and psychedelic ideas—while shaping global youth culture. Core sonic markers include electric guitar (often overdriven), electric bass, drum kit emphasizing beats 2 and 4, and emotive lead vocals. Rock songs commonly use verse–chorus structures, blues-derived harmony, and memorable melodic motifs, ranging from intimate ballads to high‑energy, stadium‑sized performances.
