I have had been on a trip to Vienna for the last few weeks. The Hofburg palace houses an antique instrument museum which to my surprise had many bassoons and contrabassoons! So here are a few but not all of the instruments on display
Entrance to Antique Instrument Museum
This Contrabassoon was built by Bradka in Vienna, this was his standard model in 1870.
This bassoon was built by Johann Stehle who at the time was considered to be one of the finest instrument makers in the German speaking regions. This instrument was an experiment as it has a tuning slide on the wing joint to lengthen the bore between the register vents and tones holes. This bassoon also has an split bell to add on a low A attachment.
This Contrabassoon was built by Bradka for the Viennese Jubilee crafts exhibition in 1888. This design differs from his previous models because of the rounded U-tubes to create less air resistance. “Bradka seems to have oriented this to a model from 1976 by Alfred Morton” (the contrabassophone maker)
