XNice Selmer Signet Bassoon Outfit- Fresh serial# 9385 matching. The wall thickness can afford to be thinner. The wall thickness of the first 10cms should‘calm down’ these vibrations by being a thicker material. If the wall dimensions at this point are too thin then the vibrations and overtones can upset the intonation making the traditionally‘difficult’ notes on the bassoon even more unstable. Resulting in a stronger tube Wall thickness can be calculated to result in specific positive acoustical compensatory characteristics The first 10cms or so of the crook has a significant effect on both tone and intonation. The advantages with this system: No seam. The tube is machine-shaped from high quality drawn brass and worked using a special process in which the conical tube is made thicker at the start(reed end) and thinner at the other instrument end(wing joint) There is no seam. N isse N Method: The Nissen method is completely new and revolutionary and bears no resemblance to the traditional production method. Therefore the design has to compromise this aspect to give both dampening and vibration in one even thickness along the crook. It would be very difficult, if not impossible, to vary the wall thickness along a tapered tube. Even a very small one, the crook is most likely un-repairable. Further problems arise later as the base metal hardens with age the seam can split. Disadvantages of this method of production are an inherent weakness of the seam leading to a possible leak.
It is then forced, with a steel mandrill inside the tube, through a soft metal block to shape the outside. Folded over a steel mandrill and braised along the seam.
Traditional Production Method: A piece of metal is cut into an elongated triangle. more the instrument and reed and therefore is of the utmost importance affecting tone and intonation.
