It seems reasonable to think that Stadler decided to have it that way because
the effect of the bulbous shape on a genuine "bell note" was too drastic.
However, does anyone know whether clarinettes d'amour frequently
had this side hole, too? It may have been a perfectly ordinary feature
at the time.
