Barlines

[Andrew Bernard]

Greetings List,

In setting a contemporary piece, I have need of being able to place 
'barlines' at various places that are not exactly barlines as such, for 
example, right after the time signature and before any notes - not 
exactly traditional notation engraving style. Other places also, where 
stretches of non-musical time occur. I have been able to write some 
postcript in markup to fake this out, but it does not seem correct or 
elegant. How should one go about dong this properly?

I tried using \partial with s rests to achieve the initial barline 
before the music, but this always seems to result in too wide a gap.

Andrew
