Subj: Re: [kl] Source of condensation inside the clarinet

In my experience, when the ambient is warm (above 25=B0C) i can play for tw=
o hours and have a only small amount of condensation in the barrel--not eno=
ugh to even cause a drip to form--and none in the upper or lower joints. I=
f it is cooler (20=B0C or below), i get all kinds of moisture through both =
joints. I don't think i drool more when it is cooler--but the instrument i=
s cooler and the moisture condenses more rapidly.

The instrument will take a temperature somewhere between the ambient and yo=
ur exhalation temperature. The greater the difference between those, the c=
ooler the instrument will be (and the more condensation will form).

But not very much cooler once the instrument is fully warmed up. Then I
suggest the water comes mainly from saliva.
