Abstract
A Bb brass horn is provided with a bell which is threaded on to the remainder of the instrument. This provides a thickening of the metal at the position of attachment and hence a relatively rigid ring circumferentially about the bell, enhancing the tonality of the instrument. The bell is detachable for storage and carrying in a relatively flat case resembling an attache case, the axis of the bell being perpendicular to the plane of the body of the instrument. The piston valves are positioned centrally of the circle or ring of the instrument for improved balance.
