244. LONG CHIMNEY (BRANCHE TUBE) IN LOW AND BASS WHISTLES TO LOWER THE TOTAL LENGTH AND MAKE THEM EASIER FOR FINGERING

 LONG CHIMNEY (BRANCHE TUBE) IN LOW AND BASS WHISTLES TO LOWER THE TOTAL LENGTH AND MAKE THEM EASIER  FOR FINGERING

The idea (and patent) of Yamaha with a long chimney or brach-tube just after the mouthpiece and of about 2/3 of bore size compared to main tube was so as to convert close-open acoustics (with odd only harmonics ) to open-open (with both odd and even harmonics). See e.g. https://www.youtube.com/watch?v=LzHasH3Acxw

But it has another effect too: It lowers the total length of the tube. This technique applied to low and bass whistles  makes them of considerably shorter length . This will make the covering of  the holes with the fingers a lot easier . Even the "pipers grip"might not be necessary now.

In  the next photo we see a  D4 clariphon (chalumeaux) with along chimney (about 1/3 of the sum-total length of both tubes . The brache has diameter about 2/3 of the diameter of the main tube) which converts it from closed-open acoustics to open-open acoustics. Nevertheless the same technique will make a Low D4 whistles with a fipple a lot shorter!

The next pictures are of corresponding Long Chimney soprano saxophones with cane reeds and sax mouthpieces as the Venova of Yamaha, or Cylisax of Linsey
