I think the range would be improved with a piston, rather than an external slide that only lengthens the tube... In the second case, I would expect only an octave (from L to 2L), but a piston can shorten the length to 0...
¡That's an idea I've never heard of! I know pistons are used in engines, but I don't understand enough about how they work to really visualize how that would apply to a woodwind or brass instrument... ¿Can you explain more?
@@traevoli Think of a slide whistle - the pin pulls on a piston that changes the length of the cylinder. The longer the cylinder, the lower the tone. en.wikipedia.org/wiki/Acoustic_resonance It also depends on if neither end, one end, or both ends are stopped (a piston would act as a moveable stop), and if the shape is conical or cylindrical (I think also a square or triangular cross section might make a difference to (compared to circular), but as the number of sides increases (pentagonal, haxagonal, etc.) the overtone series would approach that of the cylindrical cross-section. Note - this is also half-remembered physics I learned over 30 years ago...
I don't think the slide whistle design will work for this. That came 20 years after the slide sax. I'm looking at getting or 3D printing a piccolo trombone to try that.

@@traevoli I mean - maybe, maybe not. That's what experimentation is for! :)
