[Hermann the Cherusker]

When I sung in the choir for a Low Tridentine Mass (Offertory and Communion Hymns), I didn't find this distracting from attending Mass - I also winged it since I knew the songs. Same for serving Mass as an Altar Boy. When singing, it helped to be up in the choir loft looking at the Altar, rather than in the sanctuary performing to the people.

Hermann, solo work is what I do. That requires a lot more concentration than choir singing, trust me.

Well--Des gets paid for her work, and you probably didn't.

I understand exactly what she's talking about re: preparation. It does take time and practice, even if you've sung the piece a million times before (although familiarity cuts down on marking phrases, breathing, and the more rote-mechanical preparations.)

When accompanying a soloist or a choir one ALWAYS insisted on at least one run-through--if not two. And there were sections of the music where there would/could/should be discussion over how it would be performed.

That's called 'doing it right.'

As to hymn-leading as part of a choir: I confess that I have done it on a 'wing' basis, and rationalize it with the knowledge that 30 other people will be singing the same words, music, etc., and the congregation will be slightly cacophonic anyway.

Not exactly a good reason, but...
