The first note is a low C. All valves are up, relaxed lips, low air. I apologize for the odd angle.
This is a D. The first and third valves are down, low air. Be sure to kick out your slide a bit when you play this note, or else it will be out of tune.
Next comes E. Low air still, first two valves down.
This is F. The first valve is down.
This is a G. Like the low C, all valves are up, but this is a shelf higher than low C. Faster air, firmer lips.
Like the E, the first two valves are down for your A. Firmer lips, faster air.
Next is a B natural. Again, this note requires fast air and firm lips.
Finally, the high C. No valves are down, fast air, firm lips.
You're done! To go back down, just reverse the steps. Please note that the pictures do NOT accurately represent the correct way to hold your trumpet; it only applies to fingering. Thanks, good luck!
