Trombone with a displaced arm

摘要

The trombone has a slide with an inner tube fixed to a bell side (3) and fixed in one end of a tubular arm. Another end of the arm communicates with a single bell (9). The arm cuts the bell in projection when the trombone is perpendicular to the plane defined by a part of the arm and by a longitudinal axis (CC`) of the bell side. Another section of the arm is provided in the extension of the bell side.
