Rock keyboard is a keyboard-centered approach to rock in which pianos, electric pianos, organs, Mellotrons, and synthesizers provide the primary riffs, harmonic foundation, countermelodies, and solos. Instead of guitars dominating the ensemble, the Hammond B‑3 with a Leslie cabinet, Rhodes and Wurlitzer electric pianos, Clavinet funk stabs, Mellotron strings/choirs, and analog/virtual‑analog synths (Moog, ARP, Prophet, etc.) lead the texture. Players draw equally from blues, classical, and jazz vocabulary, often featuring ostinatos, extended chords, modal color, and virtuosic soloing. The aesthetic ranges from gritty overdriven organ rock to symphonic, cinematic layers and synth‑driven arena hooks.

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.
