I noticed when I went to Dakota this week my mouth was dry and I couldn't play. I got mt water bottle but the water didn't make my mouth any wetter. My mouth just turned dry ? I could play but terribly. the tonging wasn't clear. All the other brass players in my band said they had the same thing happen to them. Is this the climate affecting? If so how do I prevent this in the future when I go down to the southern and central states to play?
