The Pneumo Pro® has helped thousands of new flutists to quickly learn how to have a beautiful tone. Band directors and flute teachers love how the Pneumo Pro® facilitates the correct and consistent placement of the air column, taking the mystery out of tone production. The Pneumo Pro® can be inserted in the body of the flute which allows immediate feedback on the correct placement of the air column even while the students are balancing the flute. Best of all, the students can be silently practicing technical exercises with the Pneumo Pro, while the band or orchestra director is working with other students.
