A very nice idea, thanks!  I admit that I would never have thought of
that.  Your example is almost perfect, except that I would like to
avoid the horizontal gap caused by bass clef.  What property controls
that?  I tried to modify some `Clef' properties given in
`define-grobs.scm', but I didn't get the desired effect.
