Jazz cover refers to jazz reinterpretations of songs that did not originally belong to the jazz canon (e.g., pop, rock, R&B), as well as fresh, personalized arrangements of well‑known standards. Its hallmark is transformation: arrangers and improvisers reharmonize chord progressions, alter groove and meter (swing, bossa nova, funk, odd time signatures), reshape melodies through phrasing and ornamentation, and open the form for solos. The result keeps the recognizable core of the source tune while reframing it with jazz harmony, rhythm, timbre, and improvisational language. Historically, the practice grows out of jazz musicians’ long tradition of adapting Tin Pan Alley and Broadway songs. From the 1960s onward, covering contemporary pop/rock and later hip‑hop and electronic music became common, creating a fluid bridge between mainstream repertoire and jazz aesthetics.

Vocal jazz is a jazz tradition in which the human voice is treated as an instrument—matching the phrasing, articulation, and timbral nuance of horns or piano. Singers often improvise melodically and rhythmically, including using scat singing (nonsense syllables) to emulate instrumental solos. At the same time, many vocal‑jazz performances favor traditional, pop‑leaning song structures and clear lyric delivery, reducing the overall role of extended improvisation compared with small‑group instrumental jazz. Repertoires frequently draw from Tin Pan Alley and Broadway standards (the Great American Songbook), rendered with swing, ballad, or Latin feels.
