\break after \alternative

[Hajo Dezelski]

Hello,
always struggeling: I have 2 repeat sections. The first one endes in:

   \alternative {
            { r8 b,4 a8 g8 [fis] }
            { r4 b4 a  \bar "||" }
        }

Where do I have to put the \break to begin the second repeat section in a new line? 

I tried nearly everything, but the always the wrong ones...
