can anyone out there tell me the trick or tech. to scream on trumpet? I can play high but i can`t scream at all. is there an easy way to play it or does it just take time?

Screaming is a term commonly used for jazz. Sure you can play "high" C, D, E, F, G above the staff is "high"... I guess in terms of sound. The "scream" is pitches often called "doubles" or "triples" being they are notes above the High G on the top of most trumpet fingering charts (4th Ledger line) The pitches of these notes are so close together that transition between them is easily accomplished by just the slightest of embochure and air adjustment, and they are so damn high that they sound like you are screaming. I recommend taking a deep breath, knowing in your mind that you CAN do it, be confident, PUSH your air through the horn, fast air, no half-assing or it wont work. Do not press harder, squeeze your embochure, and practice lip slurs from the G on top of the staff to the 4th ledger line G (all the notes in between) practice these lip slurs every time you practice. When you go to play these doubles or if you are good enough triples know you can do it, be confident. Air is the key. Hope I could be of help

thanks for the tips. lip slurs up in the high E - G range should be perfect practice for me. I already know that in music it`s all about the air, but i think all i needed was some confidence.
THANK YOU...........
