Hello,
I have always LOVED how a trumpet sounds when it has a good tone, but is playing softly....But I have alot of trouble doing this.

I play with an ok tone, but when I get softer, my air has to get lower so that I can play softer, but with my decreased air then I cannot play the notes clearly.
I belive that my method of dynamic changing is wrong, so could one of you tell me how to properly change dynamics? Or is it just a matter of practice?

Thank you,

Keep the same moving air, just less of it.
Airspeed doesnt change, jsut make a little less come through the aperture.
Think of a candle. Imagine what it takes to bend the flame.
When you want louder, imagine the candle further away. For lower volume, think of teh candle as being closer.
Go get a candle and try it, you'll see what i mean.

its all about the air my friend ask your to help you with your breath support until you get better. this will help you in almost every aspect of trumpet playing
