slur across bar

[Mark Stephen Mrotek]

Hello:

 

In the following, I want to place a slur from the bes16 across the bar to the aes8.

 

\version "2.16.2"

 

{ \key des \major

  \time 4/4

   bes2-3 a4~ a8. bes16 |

aes8.  bes16 ( aes16. ) bes32 ( aes16. ) bes32

\set tupletSpannerDuration = #(ly:make-moment 1 8)

\times 2/3 { g16-1 [ bes-3 ees' ] g [ bes ees' ] bes-2 [ d'-4 f' ] d'-1 [ f' aes'-4 ] }

}

 

When I the put  aes8. in parenthesis, i.e., ( aes8. ), the error code "unexpected '(' " comes up and the complying exists.

 

What is my error?

 

Thank you for your kind attention.

 

Mark
