RE: Beam Length override not working.

[Mark Stephen Mrotek]

Rodrigo,

 

As a pianist what I wrote is clear, it may not be proper guitar, yet hopefully it might give you some idea of what to do.

Subject: Beam Length override not working.

 

Hello all. My first message here. 

I'm writing a guitar music and I have a problem I could not solve.

I'm using Lilypond for Windows (v2.18.2).

I tried to make a minimal example of my problem. Here is the code:

 

%%%%%%%%%%begin%%%%%%%%%%%%%%%%%%%%% 

\version "2.18.2"

\new Staff 

\relative c'' {

\time 2/4

  << 

            {\stemUp r16 <a' c> r8 r16 <a c> r8 }

            \\

            { \stemDown e8 e16 ees d8 d16 des }

            \\ 

            { \stemDown c,8. c16 b8. bes16 } 

  >> 

}

 

%%%%%%%%%%end%%%%%%%%%%%%%%%%%%%%% 

Following the documentation on 

http://lilypond.org/doc/v2.18/Documentation/snippets/tweaks-and-overrides#tweaks-and-overrides-altering-the-length-of-beamed-stems

I modified the code trying to shorten the beam for the D notes that are ugly:

 

%%%%%%%%%%begin%%%%%%%%%%%%%%%%%%%%% 

 

\version "2.18.2"

\new Staff 

\relative c'' {

\time 2/4

  << 

            {\stemUp r16 <a' c> r8 r16 <a c> r8 r16 <a c> r8 r16 <a c> r8}

            \\

            { \stemDown 

            e8 e16 ees  

            \override Stem.details.beamed-lengths = #'(2)  

            d8 d16 des 

            \revert Stem.details 

            e8 e16 ees d8 d16 des }

            \\ 

            { \stemDown c,8. c16 b8. bes16 c8. c16 b8. bes16 } 

  >> 

}

%%%%%%%%%%end%%%%%%%%%%%%%%%%%%%%% 

 

 

But there is no change at all. I noticed that if I overding the beam length before the first E (on the same voice) it changes the beam for the E, but not for the D.

 

Thanks,

 

Rodrigo
