How much does humidity affect playing? The reason I ask is I was recently in Chicago for vacation and packed my horns along. It seemed to me I had better endurance, my tone was better etc. Even the pedal tones came easier. Got back home and things felt worse than they did in Chicago. The humidity in Chicago is much higher than where I am from. Could the humidity be the "missing link" or could it have been something else? State of mind? Elevation? Any thought?
