Is it me or do reeds sound much better in somewhat colder temperatures (nothing below 65 degrees mind you!)

When I play my accordions in air conditioning they seem to sound much better than in the same room with very warm temperatures.

It's everyone! Humidity, density, all play a part in modulation, attenuation, and reflection. Cold air is more dense and usually less humid thus conducting or transmitting sound energy with less reflection, dampening, and modulation.
Yup.

hi Craig, before rick moves in, and i'm at least still serious: that's very interesting, you got any scientific information where you got that wisdom? i've worked with sound quite a bit: pa work, recording, gigs, the lot, and never realized this. only that when you play fiddle at high humidity gigs you'll be having some problems with a bow's hair getting too slack .... nout

My thoughts were that colder reeds contract so there's more room to vibrate. I like your theory better Craig.

Heat and humidity definately makes the accordion temporarily sound like dog sh*t and I've noticed that.

If heat and humidity made the accordion sound that bad, the poeple in Louisiana would really be in trouble. Yes, No
