Miserere Nostri for Soprano, Alto, and iPhone

I've written a piece for the Daniel Pearl Memorial Concert. The piece will be performed at the concert in Memorial Church on the evening of October 7th.

The piece applies my poly-tonal inversion model, and derives the base harmony from the Tallis masterpiece, Tallis in G, the inversion (Soprano and Alto parts) inverted in F.

You can find a nice performance of that Tallis piece here:

Tallis Miserere Nostri

This piece always seems to give me solace whenever I hear it. I don't know why.

The text comes from Psalm 123, quoted in Latin then English here:

1 canticum graduum ad te levavi oculos meos qui habitas in caelo
2 ecce sicut oculi servorum in manibus dominorum suorum sicut oculi ancillae in manibus dominae eius ita oculi nostri ad Dominum Deum nostrum donec misereatur nostri
3 miserere nostri Domine miserere nostri quia multum repleti sumus despectione
4 quia multum repleta est anima nostra obprobrium abundantibus et despectio superbis

1 I lift up my eyes to you, to you whose throne is in heaven.
2 As the eyes of slaves look to the hand of their master, as the eyes of a maid look to the hand of her mistress, so our eyes look to the LORD our God, till he shows us his mercy.
3 Have mercy on us, O LORD, have mercy on us, for we have endured much contempt.
4 We have endured much ridicule from the proud, much contempt from the arrogant.
