Re: cross-staff phrasing (slur)

Hi, Urs and Helge Kruse (sorry Helge - don't have your email address)

I managed to code cross staff phrasing with \change Staff = "right" or "left" with Helge's sample code.  I added other cross staff slurs.

Please refer to the attached. I coded bar 31, 35 and 121; but for bar 115 118 and 119 - I have time coding it.  Help is appreciated.

Thanks,
Ming

You don't need to do that at that level.
If you write music that is printed in the "right" staff you can write 
(at any time):

\change Staff = "left"

and then the current voice will continue in the other staff.
For your examples (of the first post) you would not write [half bar rest 
+ half bar music] in one and [half bar music + half bar rest] in the 
other staff but write the whole phrase in one voice and let it cross the 
staff as I have described.
This way you can write the slur without problems.

You don't need this snippet anymore. By now there is the function \shape 
in
 LilyPond that
 lets you define _offsets_ from LilyPond's decision.
So you don't have to find the absolute offsets but can work from 
LilyPond's default engraving.

Use
\shape list-of-offsets grob, that is for example

\shape #'((0 . 1)(0 . 0)(0 . 0)(0 . 0)) PhrasingSlur

for tweaking a phrasing slur to have its starting point '1' higher than 
default.
