Does a cornet have more resistance than a trumpet? I just got a '54 ambasador cornet, and i'm playing it for the first time tonight and i'm finding a bit of difficulty in reaching my normal range and maintaining a long tone. this is also my first time in fifteen years of playing that i've played a cornet. when playing a song i find myself struggling with hitting higher notes, but when i go over the same song with my ambassador trumpet i have no problem. anyone have any clues?
