9Keith Johnson retired in 2014 from the University of North Texas, where he was Regents Professor of Trumpet and was honored with the Distinguished Teaching Professor award. Johnson wrote more than thirty articles, two pedagogical texts, and two method books. During his career, he presented masterclasses at universities and conservatories throughout the United States and worldwide.

Johnson's former students hold positions in universities, orchestras, and military ensembles in over a dozen countries. In The Art of Trumpet Teaching, his students describe Johnson's teaching approach and tireless work to help each person succeed. Along with Johnson's biography and studio stories, Leigh Anne Hunsaker presents an extensive collection of pedagogical concepts from Johnson's six decades of teaching. Johnson's hallmark pedagogical tenets, along with much practical advice given to his UNT students, provide a teaching and reference handbook for a new generation of teachers and players.
