Dr. Arthur Frackenpohl has made a significant contribution to the success of the Canadian Brass through his arrangements and transcriptions for brass quintet and brass ensemble. This ongoing collaboration of more than 20 years has produced music for 21 recordings on the CBS Masterworks, Phillips, and RCA labels, and has provided concert repertoire for the world famous Canadian Brass Quintet. The author develops a biography to outline the elements in the life of this composer and arranger that shaped his musical talents and ideas, and shows how his interaction with professional brass players influenced his work. A history of the brass quintet is followed by a description of the relationship between Dr. Frackenpohl and the Canadian Brass and the key factors to its success. A descriptive analysis of a selected transcription and an annotated bibliography of Dr. Frackenpohls arrangements and transcriptions for the Canadian Brass is supplemented with a bibliography of his complete works for brass.
