In the 70s and 80s contrabass flutes began to be built in Japan and The Netherlands, largely for use in flute ensembles around the world. As the design greatly developed since those early days, and more builders around the world have been added, the contrabass flute has come into its own as a unique instrument to enjoy and explore.
Next to a general improvement in standard flute components such as the embouchure, keyworks, scale and the shape of the tubing (combination of conical and cylindrical tubes), recent improvements have seen a larger range, open holes and quarter tone additions. I believe that the instrument has developed to around 75 to 80% of its pinnacle, and till now it has been exciting for me to witness and be a part of its refinement.
