For years he has devoted himself more and more to the activity of soloist and teacher with appearances in Europe, the Americas, the USSR and the East. His intense publishing activity gave him a great success with his Practice Books for the flute, the most original flute method that has been conceived in recent years.
From 1968 to 1991 he was director of the Flute Department of the Royal Northern College of Manchester where he took over the class of Geoffrey Gilbert. Here he established himself as one of the leading flutists in the field of teaching, not only in England, but also in Europe and the United States.
