I played my pennywhistles and a low D with a group for three years
and I often noticed the same thing, although I think I found
an explanation for it later, while recording myself and my
friends at home.
While we were using a tuner program on my computer we
noticed that the whistles sometimes produced only two or
three peaks in the spectrum, sometimes only one in the 2nd
octave. The fiddle covered those with even larger peaks.
That's why the ear registered only the fiddle, the whistle
being completely "cancelled out".
My friend, who is doing his Ph.D. at the Institute of
Acoustics at the same faculty as I'm studying confirms this
theory (although in many more words :))), using Ph.D.
language and some maths :)))
I wondered if it'd be possible to tune some instruments
a tiny bit sharper to help the ear distinguish them without
making them sound too far off. (I heard guitarists do this
sometimes if playing in duos).
I haven't yet had a chance to play my pipes properly in
public, so I don't know about the chanter's reactions :))
