Terence Fletcher is the abusive jazz music director at Shaffer Conservatory jazz band. Despite his distinguished reputation, Fletcher is actually an abrasive, vulgar, and ruthless instructor who issues severe physical and psychological abuse to students for even the most minuscule mistake. Fletcher is focused on his own volition. Egotistic, brutal with a "the ends justify the means" mentality. Fletcher does not try to "coach" people, he imposes his volition on people without any further ado.
