Longa (Middle Eastern music)
A longa is a Turkish / Eastern European dance, that was later introduced into Arabic music and is often performed at the end of a muwashshah.
It generally uses an iqa' equivalent to 2/4, with several sections called khanat, each followed by a taslim. The last khana is generally in 3/4.
A common form of longa is longa Riad in Nahawand scale which is composed by the Egyptian composer Riad Al Sunbati in the maqam Nahawand.
