Novelty is a branch of popular song that foregrounds a "novel" hook—gimmicks, topical jokes, exaggerated sound effects, or playful pastiches—designed to grab immediate attention and often to amuse. It overlaps with comedy songs and musical parody, but not every humorous song is a novelty; the emphasis is on the conceit itself and its instant recognizability. The term emerged in the Tin Pan Alley era as one of the three big divisions of commercial popular music (alongside ballads and dance numbers), and the style surged in popularity in the 1920s–30s, with later revivals in the 1950s–60s and recurring viral waves in the internet age.

Barbershop is a four-part, a cappella vocal harmony style built around a lead melody with tenor, baritone, and bass parts that lock chords to create "ringing" overtones. Its hallmark sound emphasizes dominant-seventh-rich harmony, homophonic textures, and expressive devices such as swipes, echoes, and tag endings. The repertoire traditionally draws on late-19th- and early-20th-century American popular songs, with lyrical themes that are romantic, sentimental, or humorous. Performance values center on unified vowels, precise tuning (often approaching just intonation), balanced resonance, and coordinated interpretation.
