It is first useful to specify that the impact of the saxophone ligature or clarinet ligature is minor compared to that of the saxophone or clarinet mouthpiece or the instrument itself. In reality, this impact will be most noticeable by intermediate or advanced musicians. The ligature will affect the musician's timbre, accuracy and comfort.
The metal ligature emits a more stamped sound, the contact surface with the saxophone or clarinet reed : contact complete, contact partial, plot or rail is decisive insofar as it conditions the emission facility. Indeed, the smaller this surface is, the easier the emission is because the reed can vibrate.
End of gather the best of metal ligatures and tissue ligatures, Vandoren set up leather ligatures with pads different (metal, firm leather and soft leather)
There are two models of ligatures: the standard standard model with the screws upwards either opposite the reed and the inverted <strong model with the screws downwards or on the reed side. Reverse ligation minimizes contact with the reed.
