small print

[Simon Bailey]

hi again,

something i have seen quite often in orchestral pieces is that other
voices are sometimes printed in small print during rests of a certain
instrument. for instance, in a piece i played recently, the 1st horn
part was printed in small print in the 1st trombone (see the picture at
http://simon.icsp.at/musicextract.jpg). 

how can i duplicate this with lilypond? i know how to combine the two
threads, but i don't know how to make the size of the printed elements
smaller...

any ideas?

thanx,
simon.
