Thanks!

However, my code doesn't work properly.  I attach a patch and the
output i get from the following input:

{ \clef "treble_8" c' }
{ \clef "treble^8" c' }
{ \clef "bass^8" c' }
{ \clef "alto^8" c' }
{ c' \clef "bass^8" }
{ \clef "bass^15" c' }

I don't have any idea why change clef isn't small.  I know why the
octavation in the last line is wrongly aligned, but i don't know how
to fix it (i tried manipulating X-offset instead of X-alignment but it
didn't work).  Could you point me in the right direction?

cheers,
Janek
