A concert is a live music performance in front of an audience. The performance may be by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, choir, or band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, amphitheatres and parks, to large multipurpose buildings, such as arenas and stadiums. Indoor concerts held in the largest venues are sometimes called arena concerts or amphitheatre concerts. Informal names for a concert include show and gig.
Regardless of the venue, musicians usually perform on a stage (if not actual then an area of the floor designated as such). Concerts often require live event support with professional audio equipment. Before recorded music, concerts provided the main opportunity to hear musicians play. For large concerts or concert tours, the challenging logistics of arranging the musicians, venue, equipment and audience (ticket sales) are handled by professional tour promoters.
While the first concerts did not officially appear until the late 17th century, similar gatherings had been around throughout the 17th century at several European universities, such as Oxford and Cambridge. Officially, though, the first public concerts that required an admission were created by the English violinist, John Banister. Over the next few centuries, concerts began to gain larger audiences, and classical symphonies were very popular. Finally, after World War 2, these events changed into the modern concerts that take place today. An example of an early, post-WW2 concert is the Moondog Coronation Ball.
The first known occurrence of concerts where people are charged admission took place at violinist John Banister's home in Whitefriars, London in 1672. 6 years later in 1678, a man by the name of Thomas Britton held weekly concerts in Clerkenwell. However, these concerts were different. Before, you had an admission that you paid upon entering the building where the concert was held but at Britton's concerts, patrons purchased a yearly subscription to come to the concerts.
