It's probably easier than you think. The fingering is essentially saxophone (close enough that A. Sax sued the sarrusophone makers repeatedly for patent infringement). Sure, it has a double reed, but it is wide enough that it doesn't take too much getting used to.
All three daughters play horns: oldest = flute/picc; middle = alto sax; youngest = clarinets (soprano, bass) and sax (bari).

My eyes are closed only because my eyes are always closed in photographs. Even my security badge took 4 tries (and that was taken with a computer webcam - no flash). I apparently have pretty fast eyelids (at least part of me is fast)...
