Trumpet no end: How has high register trumpet playing evolved in jazz?

Upper register playing is an ability that has made its way into normal trumpet technique through its prominent use in jazz. It is a difficult skill to master, requiring the utmost technical proficiency and physical manipulation, and it is seen by many as the pinnacle of trumpet technique. In this thesis I will analyse different aspects of high register trumpet playing beginning with an examination of the physiology involved and why it is so crucial to sustained playing in this register. I will then look back to the Baroque, classical and romantic periods to see how high trumpet playing was practised during these periods to determine if a comparison exists in relation to its use in modern times, and why the use of the technique appeared to die out at the beginning of the 19th century. Finally, I will trace the technique's resurgence in popularity in jazz and examine how a new breed of players would overcome the physical difficulties needed, bringing a new level of virtuosity and showmanship to the instrument.
