zigzag staffline

[Gagi Petrovic]

Dear Ponders, i'm working on a composition where i'm in need of a custom 3-lined-staff with a zigzagged (like the glissando style, see attachment) middle line. Is it possible to make a small adjustement to the code below, or should i start doing some serious tweaking? Any pointers are well appreciated. Thank you very much in advance!

Kind regards, Gagi

\version "2.16.1"  

 

\relative c' { 

 \override Staff.StaffSymbol #'line-positions = #'(-4 0 4) 

 \override Staff.StaffSymbol #'ledger-positions = #'(0)  

a'8 g f e e 4 c| c'2 c

}
