“A wandering minstrel I-
A thing of shreds and patches
Of ballads, songs and snatches”
(Gilbert and Sullivan, The Mikado)
Wandering music is a highly effective way of allowing the musicians to engage directly with the guests particularly at things like drinks receptions, it also negates the need for expensive PA systems. It can be of almost any type from classical to jazz, acoustic guitar playing pop to high energy Mariachi bands. Don’t stick your band in a corner, get them out into the middle of the party and allow them to create the flow!
