The set of tubes are finished.  They have different notes and sounds.  The tubes were played with a saxophone reed and “trumpet-style”.  The tone gets less clarinet like and more saxophone like as the cone part gets larger.  With the saxophone reed it was possible to get lower and higher harmonics for the more conical shapes.  Using a lip reed it was not possible to get the lower harmonics.  Also with the sax reed, it was more difficult with one of the middle tubes (about half cylinder – half cone) to hit the harmonics cleanly.  We experienced a similar problem at the beginning of the summer with our homemade clarinet (from rings).  As we increased the cylinder to conical ratio the harmonic structure changed. 20160825_091944_HDRThe videos of the tubes being played can be seen here:
