Fog Snow...
...followed by rain.
Practice makes perfect, and I am now up to about 6 minutes straight. (In my defense, twice a day.) I'm having trouble with the b above middle c because that requires almost all holes to be filled and almost all keys to be pressed, along with a perfect embouchure. Mostly what I'm getting now are squeaks, and Pax thinks those are almost as bad as gun shots.
