History of A Cappella
A cappella music was first heard in churches. One example a cappella style music that was performed in churches is the Gregorian chants. Some churches do not believe that instruments should be used inside of chapels, and so they use a cappella arrangements instead of traditional accompaniments. Some Jewish and Muslim services use a cappella music, as well. A great deal of the music from the Renaissance was also a cappella.
In the 1990s, a cappella began to grow in popularity as more groups began to emulate instruments as part of the performance. This allowed groups to take already popular songs and change the arrangements. This was done primarily in collegiate groups throughout the country, though some professional groups did this as well. Generally, one or two people will hold the bass and drum sounds while the other singers will emulate the sounds of different instruments. It creates a very full sound.
A Cappella Musical Theater ??
There have been just a few performances of musical theater with entirely a cappella music. One of these was Avenue X, and it was performed in 1994. More recently Perfect Harmony and In Transit were performed in off-Broadway theaters. Both of these productions took place in 2010.
Barbershop Style Music
In addition to the collegiate style a cappella music, barbershop style music has been very popular throughout the United States. This style of a cappella focuses on harmonizing and originally started with men's groups. The style got its name because the first groups were started in barbershops. Although this style was started in America, it has grown in popularity and spread throughout the world.
