Halleluya halleli nafshi (Psalm 146)

This chant is an example of Hebrew psalmody that consists of a flexible melodic formula in two sections with fixed beat, yet with changing meter. This is one of the oldest genres of Sephardi liturgical music. It is used for singing psalms on diverse occasions, except in the introductory Psalms of the Sabbath morning service (pesuqei de-zimrah or, in the Portuguese terminology, zemirot). A similar psalmodic formula can be heard in Sephardi synagogues in Italy.
