Metal guitar is a guitar-centric branch of heavy music that spotlights virtuosic lead playing, high-gain tones, and tightly synchronized rhythm parts. It emphasizes speed, precision, and advanced techniques (alternate and economy picking, sweep arpeggios, legato, tapping, wide vibrato, whammy-bar phrasing, and hybrid picking). Harmonically, metal guitar often draws on modes and scales with a dramatic edge—harmonic minor, Phrygian dominant, diminished and whole‑tone collections—alongside modal riffing (Aeolian, Phrygian) and pedal-point figures. Rhythm guitars are commonly double- or quad‑tracked, palm‑muted, and locked to aggressive drum patterns, while leads soar over dense rhythm beds with saturated sustain. Although it intersects with instrumental rock and many metal subgenres, “metal guitar” specifically spotlights the role of the guitarist as the principal voice, whether in instrumental pieces or guitar-forward band contexts.

Shred (often “shred guitar”) is a virtuosic, high-speed style of rock/metal lead guitar playing distinguished by extreme technical facility and showmanship. It emphasizes rapid alternate picking, sweep/economy-picked arpeggios, legato runs, multi-finger tapping, wide-string skipping, whammy-bar articulation, and precise synchronization between both hands. Harmonically it often draws on minor tonalities (especially harmonic minor, Phrygian dominant, and diminished), neoclassical cadences, and chromaticism, while rhythm sections supply a hard rock or metal backbeat at high tempos. The sound typically uses high-gain distortion, tight compression, delay/reverb for sustain, and articulate amp/EQ settings so fast passages remain clear. Although closely associated with 1980s metal aesthetics, shred persists as a technique-forward idiom across instrumental rock, power/progressive metal, and online guitar culture.

Neoclassicism in music is a 20th‑century movement that revived forms, genres, and aesthetics from the Baroque and Classical eras, but reframed them with modern harmony, rhythm, and orchestration. It emphasizes clarity, balance, objectivity, and contrapuntal craft, often rejecting late‑Romantic excess while retaining a tonal or modal center enriched by dissonance, bitonality, and crisp rhythmic drive. Typical hallmarks include neobaroque dance suites, neoclassical sonatas and concerti, chamber‑oriented scoring, clean textures, and a dry, anti‑rhetorical performance style.
