A concert is a live performance (typically of music) before an audience. The performance may be by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, a choir, or a musical band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, entertainment centres and parks to large multipurpose buildings, and even sports stadiums. Indoor concerts held in the largest venues are sometimes called "arena concerts". Regardless of the venue, musicians usually perform on a stage. Concerts often require live event support with professional audio equipment. Before recorded music, concerts would provide the only opportunity one would generally have to hear musicians play. Informal names for a concert include "show" and "gig".

The nature of a concert will vary by musical genre and the individual performers. Concerts by a small jazz combo or small bluegrass band may have the same order of program, mood, and volume, but vary in music and dress. In a similar way, a particular musician, band, or genre of music might attract concert attendees with similar dress, hairstyle, and behavior. For example, the hippies of the 60s often toted long hair (sometimes in dread lock form), sandals and inexpensive clothing made of natural fibers. The regular attendees to a concert venue might also have a recognizable style, comprising that venue's "scene".
