interview comment from 2005 Elizabeth: I performed Cantata 51 before it was recorded but never where the Chorale and Alleluia were the same tempo and that worked perfectly. Those two tempos are identical. There's no tempo change indicated. The conductor did it that way and it worked.
Boy was I glad I had practiced singing scales, quads, and triplets with a metronome in good time. That is what the music demands. The conductor and I were able to deliver that because I'd practiced the techniques and could sing my melismas evenly.
When all the notes are created differently the melismas get choppy. The singer has to smooth out the legato and sing the notes evenly in rhythm. That has to be trained. When you get to your professional thing and that's what the conductor wants and what the music demands you want to know that you are technically ready to deliver. If there is a lack of precision it means the singer has neglected their exercises.
