This moving and beautiful piece is presumably a setting of the first two verses of Ps 42, and is presented here with editorial underlay. The piece is important in the transition from the florid pre-reformation style to the imitative Renaissance style, and was the head of an entire genre of bipartite psalm motets stretching to Gibbons' O Clap Your Hands of 1622, but only here is the bipartite form explained by the two verses being set. The cleffs imply upward transposition, of a tone in this case, and a further transposition is necessary because of the higher pitch, here a semitone. The alto parts are singable by tenors. The counter tenor did not appear in England until the 17th Century.
