Rocksteady is a Jamaican popular music style that emerged in the mid‑1960s as a slowed‑down, more soulful successor to ska and the direct precursor to reggae. It retains ska’s off‑beat guitar/piano "skank" but lowers the tempo, brings the bass to the foreground, and favors expressive vocal harmonies. Typically recorded by small studio bands with guitar, electric bass, drums, piano/organ, and occasional horns, rocksteady emphasizes melodic, inventive basslines, tight rhythm guitar, rimshot/side‑stick drums, and sparse horn figures. Lyrically it ranges from tender love songs and yearning ballads to rude‑boy narratives and social commentary. Its concise arrangements and groove‑driven feel make it both danceable and emotionally resonant.

Military cadence (also called a cadence call or “jody call”) is a traditional call-and-response work song used by military personnel while marching or running. It is designed to synchronize footfalls and breathing, reinforce unit cohesion, and maintain a steady training pace. Cadences typically feature a single leader (caller) who improvises or selects verses, with the group responding in a fixed refrain or echoed phrase, often over a simple, repetitive rhythmic pattern aligned to the movement.
