Today at the 10:00 mass for prep we played Marty Haugen's setting of Psalm 141 arranged for choir, piano, and two violins.  It's a gorgeous cannon in an absurd key (E-flat minor) and was such a musical high I am only now coming down! Playing it was like riding rolling ocean waves, cresting and falling, always in motion.  The refrain was "Let my prayer rise up like incense before you..."  I still feel it reverberating in me

At the 12:00 mass we played a stripped-down version with just the cantor, piano, and violin.  The third time through I had to switch to the female choir part to do the round, and missed the entrance on the refrain the first two times.  I got it on the third time, and I'm sure nobody knew I was supposed to play but didn't.
