Jerome (Jerry) Callet was a deeply frustrated trumpet failure for the first 25 years of his life. Despite studying all the accepted methods of the time, and with the most renowned teachers, the harder he worked the worse he played.

Rather than give up, as most would, Jerome turned his attention to discovering why no one could teach him how to become a fine trumpet player. Was it even possible to develop a world class embouchure and sound? Or, is a good embouchure due only to natural ability granted from especially good genes?

His first breakthrough came from studying the chops of great players via performance photos. He soon recognized that most great players were forming their embouchures in a manner very much contrary to the methods he’d been taught.

He also discovered that none of the world's greatest trumpet players, while following accepted methods, could teach their own children to play well. Jerome reasoned that even if these exceptional players fully believed what was being taught to beginners, they themselves played differently.

From these beginnings and 50 years ensuing study, Jerome Callet began to dramatically change brass instruction. Simultaneously, he designed new mouthpieces that both aided development and greatly improved performance. And his last creations, his NY Soloist and SIMA trumpets, fulfilled the final part of his lifelong mission. With a richer, fuller, and more vibrant sound, a denser and more concentrated core, superior intonation, and an ease of performance in all registers, Jerome Callet’s Sima and NY Soloist trumpets fulfilled his final dreams. In the end, his fantastic chops, mouthpieces, and trumpets made his difficult trumpet journey a true success story, a story that is now recognized worldwide.
