Entre gris clair et gris foncé

Variety is a radio format rather than a single musical genre. It is built on playing a broad, eclectic mix of music across styles and eras, often interwoven with talk, community announcements, sports, news, and specialty programming. In practice, variety (especially in its free‑form expression) minimizes rigid playlists and tight rotations, grants wide autonomy to on‑air hosts, and emphasizes local culture, discovery, and serendipity. It is most commonly associated with smaller, non‑commercial broadcasters—college radio, community radio, and some high‑school or public stations—where a program director exercises minimal influence beyond regulatory compliance. The result is a platform where punk can sit next to jazz, folk, hip hop, experimental, classic rock, and global music—sometimes all within the same block. Because variety is a programming philosophy, it does not have signature rhythms or harmonies of its own; instead, it curates many genres to create a diverse listening experience.

Pop rock blends the hook-focused immediacy of pop with the instrumentation and drive of rock. It prioritizes catchy melodies, concise song structures, and polished production while retaining guitars, bass, and drums as core elements. Typical pop rock tracks use verse–pre-chorus–chorus forms, strong vocal harmonies, and memorable riffs. The sound ranges from jangly and bright to mildly overdriven and arena-ready, aiming for radio-friendly appeal without abandoning rock’s rhythmic punch.

Pop is a broad, hook-driven style of popular music designed for wide appeal. It emphasizes memorable melodies, concise song structures, polished vocals, and production intended for radio, charts, and mass media. While pop continually absorbs elements from other styles, its core remains singable choruses, accessible harmonies, and rhythmic clarity. Typical forms include verse–pre-chorus–chorus, frequent use of bridges and middle-eights, and ear-catching intros and outros. Pop is not defined by a single instrumentation. It flexibly incorporates acoustic and electric instruments, drum machines, synthesizers, and increasingly digital production techniques, always in service of the song and the hook.

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.
