For a revision of the reeds taxonomy (also in the light of some new discoveries)

The discovery of various aerophones whose reed is a tense membrane (marginal instruments, certainly, newly constructed, and which exist mainly as a consequence of the progress made in the production of elastomeric materials) have compelled me to review the class of aerophones, and in particular free idiophonic interruptive aerophones, and advancing my own revision of the articulation of 412.1.I propose the following articulations for idiophonic interruptive aerophones. 412 Interruptive free aerophones 412.1 Idiophonic interruptive aerophones or reeds 412.11 Flexible beating reeds 412.111 Concussion reeds 412.111.1 Idioglot concussion reeds 412.111.11 Blade concussion reeds 412.111.12 Flattened concussion reeds 412.111.121 End-blown idioglot concussion reeds 412.111.122 Side-blown idioglot concussion reeds 412.111.2 Heteroglot concussion reeds 412.111.21 Tied concussion reeds 412.111.22 Concussion reeds with staple 412.112 Percussion reeds 412.112.1 Idioglot percussion reeds 412.112.11 Upper cut idioglot percussion reeds 412.112.12 Lower cut idioglot perc. reeds 412.112.2 Heteroglot percussion reeds 412.112.21 Upper cut eteroglot percussion reeds 412.112.22 Lower cut eteroglot perc. reeds 412.12 Flexible free reeds 412.13 Stretched reeds 412.131 Ribbon reeds 412.131.1 Ribbon reeds without frame 412.131.1 Ribbon reeds with frame 412.132 Membrane reeds 412.132 Percussion membrane reeds (complete membrane reeds) 412.132 Free membrane reeds (cropped membrane reeds)422 Reed aerophones 422.1 Double reed instruments 422.11 (Single) shawms 422.111 With cylindrical bore. 422.111.1 Without fingerholes. 422.111.2 With fingerholes. 422.112 With conical bore 422.12 Sets of shawms 422.121 With cylindrical bore. 422.122 With conical bore. 422.2 Single reed instruments 422.21 (Single) clarinets. 422.211 With cylindrical bore. 422.211.1 Without fingerholes. 422.211.2 With fingerholes 422.212 With conical bore 422.22 Sets of clarinets. 422.3 Reedpipes with free reed 422.31 Single pipes with free reed. 422.32 Double pipes with free reeds. 422.4 Percussion membrane clarinets 422.41 (Single) percussion membrane clarinets 422.42 Sets of percussion membrane clarinets
