This psalm is designated a "Shiggaion" in its superscription, whatever that is. Strong's Concordance suggests it is "perhaps a wild passionate song with rapid changes of rhythm." Admittedly, this new setting—("Chadash" simply means "new")—has no dramatic rhythmic changes, but the intervals are a bit wild, and the sassy Dsus4/D trill (I'm talking chord shapes here, not actual notes) lends it a feel that seems worthy of the designation: shiggy. [But, please, let's not confuse it with the "shig" that is going on in west coast cities right now. Lord, have mercy.]
Year D, by the way, recommends Psalm 7 for the Great Vigil of Holy Saturday and for 11th Ordinary.
