 The American music industry is dominated by large companies that produce, market, and distribute certain kinds of music. Generally, these companies do not produce, or produce in only very limited quantities, recordings in styles that do not appeal to very large audiences. Smaller companies often fill in the void, offering a wide variety of recordings in styles ranging from polka to salsa. Many small music industries are built around a core fanbase who may be based largely in one region, such as Tejano or Hawaiian music, or they may be widely dispersed, such as the audience for Jewish klezmer.
