I do my own tuning and I have my #3 stop tuned very slightly wet (5 cents). I have noticed that it seem louder than when the #3 was dry tuned. Is it just my bad hearing? Five cents wet is hardly noticeable from a dry tuning but it seem louder when I play cajun and also sounds a lot better when I play conjunto with the #1 and #2 stops closed.

Actually
DRY is louder.

The drier the accordion, the more "sypathetic" reed vibration you get and it is actually is a little louder.

A dry accordion will also sound louder because the pitch is less defused.

Think on it this way.
Which sounds louder, three bagpipes playing the same note at once, or three bagpipes playing three different notes at once?

My understanding is that most "dry" tunings are not exactly matched. I would still call a 5 cent difference "dry". A true "wet" musette is much greater.

That's pretty much how they are tuned these days. 5 cents off getting to be standard.

there is a psychoacoustic reason why wet
might sound louder

that is this: when the brain hears the
same sound, it tends to tune it out
the longer it lasts

wet is sort of contiually varying

wle.

The psychology of sound! I love it!

Gee, how come it never works with guitars?

The guitar player drunes on and on, and I can never tune him out!
