Thumri is a common style of light classical music said to have begun with the court of Nawab Wajid Ali Shah, 1847-1856. There are three types of thumri: Punjabi, Lucknavi and Poorab ang thumri. The text is romantic and devotional in nature, and usually revolves around a girl's love for Krishna. The language is a dialect of Hindi called Brij bhasha. This style is characterized by a greater flexibility with the rag. The compositions are usually set to keherewa of 8 beats, addha tal of 16 beats, or deepchandi of 14 beats. It arose in popularity during the 19th century.
