How a Flute is MadeManufacturing the head jointThe head joint, which determines the timbre and the pitchThe surface of the material is smoothed with sandpaper and polished with a buffing cloth. A high-precision pipe, whose dimensions are accurate to the order of microns, is then produced. This process is crucial to determining the timbre and the pitch of the flute. The brazing of the embouchure holeThe lip plate and the riser are brazed to the head joint. The embouchure hole is undercut for greater volume and a projecting sound. This is performed manually on high-grade, handmade models. The head joint is immersed in a plating solution and electroplated with silver.
