nice thread!
here goes------
1. Hold trumpet as normal;
2. Tilt 90 degrees to the left (i.e., counter clockwise) so that the valves are horizontal, with the valve buttons pointing to your left;
3. Angle the bell up a few degrees;
4. Press down 3rd valve and blow (some folks find it best to remove the mouthpiece before blowing);
5. Press down 2nd valve and blow;
6. Press down 1st valve and blow;
7. Rotate 90 degrees counter clockwise so that valve buttons are pointing straight down;
8. Tilt bell downwards and lots of water runs out clearing all parts of the instrument!
