Iqa‘ Sudasi (whose name means based on the number "six") is a very popular iqa‘ to accompany folk line dances from Lebanon and Palestine, like the Dabke. It can modulate to 3 back-to-back measures of Iqa‘ Malfuf.
An alternative form of Iqa‘ Sudasi starts with 3 consecutive dum-s, and is commonly used in Lebanese dabke songs.
