doo-wop

The term 'doo-wop' is a classic example of onomatopoeia, emerging directly from the vocal music it describes. It originated in the United States in the 1950s, coined to name a popular style of rhythm and blues where vocal groups used nonsense syllables to create rhythmic bass lines and harmonic textures. The word itself phonetically mimics the characteristic two-part scat singing—"doo" representing the sustained bass note and "wop" the percussive closing sound—that was a hallmark of the genre. This imitative formation bypasses traditional morphemes, as the term's logic and meaning are derived entirely from its sonic resemblance to the music's distinctive vocal improvisations.

This is a simplex word. It is an onomatopoeic compound, imitating the characteristic vocal sounds (e.g., "doo-wop", "shoo-doo-be-doo") used for rhythmic backing in this music style.
