Dear Sandra and vocalists,

blowing out the mic is not bad: it means that the mic
is badly used and/or placed. The hooty high pitched
sound, will very likely be some kind of feed back: the
sound you emit is picked up by the same or another
microphone, then amplified, then this amplified sound
is being picked up as well together with your voice,
and amplified and so on. This you can compare with the
situation where soldiers march over a bridge in a
certain rhythm which equals the own vibration
frequency of the bridge, which can cause the bridge to
vibrate heavily or even crash.

(So some sound waves can cause a strong reinforcement
of a vibration, this is also what makes you brake a
glass or window when singing, it is not so hard, just
a matter of the right frequency=pitch and keeping it.)


Because your voice projects well, the voice and it's
amplification is much more likely to be picked up by
other microphones, and besides that you will be
emitting other frequencies than non-trained voices
(your ring or ping or singers's formant) so the sound
technician might have a lot of problems with you, that
are only caused by the fact that you sing well. Of
course you might sing louder as other people, but you
wrote it happens if you sing piano as well, so that's
not the main issue. Besides that there is no 'singing
too loud' for a microphone, at least not if you don't
place it almost in someone's mouth.

My question: does this choir really need microphones,
are the church acoustics so bad? I can hardly imagine,
all churches I've seen had very good acoustics (ok, in
Europe, I admit). I think a choir that sings with mics
will take away the need for the untrained voices to
learn how to sing technically well, to the expense of
tone quality and the difficulties you get when adding
people that can sing.

About the studio and home-recording situation: even a
small trained voice can reach enormous differences in
loudness, so it can be difficult to adjust the level.

To go back to the choir problem: if possible, I would
try to persuade the other choristers to take singing
lessons and get rid of he microphones and in the end
everybody will be happy.


Best greetings,

Dre
