Staves/Voices question

[Jule Slootbeek]

Hi

I'm typesetting an choral (Solo + SATB) arrangement of "Sometimes I feel 
like a motherless child" and sofar i have typeset most of the part 
individually

solo =
        \notes
        {...}

etc.

my question is if that the song starts out for 10 measures with the 
soloist. and then the Tenors and Basses come in.

Is there a way to leave the tenor and bass bars out until the 10th 
measure, so the piece starts for 10 mm with only soloist and piano, then 
at measure 10 the tenor and bass bar are added.

any ideas?

Jule
