I'm still not perfect on certain bits in some of the bat-out-of-hell-speed movements--need to figure out the best place to breathe in some of those long runs, for example, and check at home and make sure I have them clean. And then memorize as much as possible.
Last night we worked on "Et resurrexit" then ran "Qui tollis," one of the slow, dark choruses which apparently sounded great. We then worked on and ran the "Sanctus" and "Osanna" sequence, then we ran the first "Kyrie," which opens the entire piece.
I have loved the opening of Bach's B minor mass since I first heard it on cd, and singing it is extraordinary. I actually got a rush of happy adrenaline right before we started the movement. I was still flying when I went home at ten.
