Musical flute in accordance with Boehm system

摘要

The flute foot piece (3), alone or together with the end area of the flute middle piece (1), has an axial through-passage (2,4) widened in cross-section in relation to the commencement area of the flute middle piece (1). The flute middle piece has a through passage (2) formed as a cylindrical hole with approximately 19 mm. diameter. The through passage, at the end of the flute middle piece and/or flute foot piece, is widened in relation to the diameter of the commencement area of the flute middle piece by 1/10-10/10 mm. The cross-section of the through passage in the flute foot piece is widened conically to the foot end. The cross-section of the through passage (4) in the flute foot piece at the foot end forms a trumpet-type widening.
