I’ve been listening iPod a lot at work the last couple days, since

I’ve been doing a bunch of grungy work, and I set up a playlist with
lots of holiday and Christmas music, including a recording from WCRB
of the Holiday Pops concert I sang in a couple years ago. This is
great—it’s fun music that I know and enjoyed singing, and is
generally associated with good memories—with one exception.

I’m loud, and a high soprano, so in a couple places I can hear myself
as part of the choir. My gut reaction to this is horror—I’m
spoiling the choir!

A little more thought has me questioning that: is it bad that I can
hear me, if I sound okay? Is it always bad to hear one voice out of a
choir?

What about if I hear "me", but it’s actually 3-4 people who were
matching my usual tone? Or who have a similar one?

What about on the super-high, super-loud end-of-song notes where I’m
one of only a couple people singing that note?

I’m probably overreacting to this—the concert is generally awesome,
and they wouldn’t have let me in the choir if I’d sucked that
badly—but I do worry about these things.
