The Cambridge Dictionary

Busking is the practice of performing in public places, for gratuities, which are generally in the form of money and edibles. People engaging in this practice are called buskers, street performers, street musicians, minstrels or troubadours.

Performances can be just about anything that people find entertaining, including acrobatics, animal tricks, balloon twisting, card tricks, caricatures, clowning, comedy, contortions, escapology, dance, singing, fire skills, flea circus, fortune-telling, juggling, magic, mime, living statue, musical performance, puppeteering, snake charming, storytelling or reciting poetry or prose, street art such as sketching and painting, street theatre, sword swallowing.

One-man bands have historically performed as buskers playing a variety of instruments simultaneously. One-man bands proliferated in urban areas in the 19th and early 20th centuries and still perform to this day. A current one-man band plays all their instruments acoustically usually combining a guitar, a harmonica, a drum and a tambourine. They may also include singing. Many still busk but some are booked to play at festivals and other events.

In old German buskers were known as Minnesingers and Spielleute.

The word "busk" probably comes from the Spanish "buscar", meaning "to seek" – literally meaning to seek fame and fortune. Buscar in turn evolved from the Indo-European word "bhudh-skō" (to win, conquer) via the Celtic word "boudi" (victory).
