Hi Andrew (and others on the mailing list):

 

Thanks for taking the time to write your suggestion.

 

I pasted your recommended solution into Lilypond. (I also installed Lilypond 
2.19.38 in Windows to make sure that I am running the same version.)

 

When I compile, I receive a warning about an unterminated tie for the soprano 
in measures 1 and 2.

 

To resolve the situation, I tried reversing the order in the temporary voices 
in measure two. In other words, I put the c in the upper voice and the a flat 
in the lower voice. This rearrangement did not get the tie to appear.

 

Can you or anyone else suggest how to make the tie appear in the soprano c in 
the two measures?

 

Thanks to anyone who can offer a suggestion.

 

Joe Srednicki

Subject: Re: Parallel music, adding a voice, stem not appearing

 

Hi Jospeh,

 

An erstwhile organist myself, hopefully I can give you an answer.

 

For me, while parallel music is described in the NR, for pieces of any length I 
find it too hard to untangle what voice is what. Better in my opinion to use 
explicit voices outright and be done with it. Then you have at your control all 
the lilypond machinery for adjusting voices, including offsets and so on. 
Generally you know when you have to introduce highly specifically coded tweaks 
for column offsets to get things to work that you are on the wrong track. 
Lilypond is very good at working out layout issues when you use the standard 
techniques.

 

Here is a rewrite of your score, using an absolutely standard multi voice 
technique for piano, or organ. I put the voices together in the staves they 
normally live in, but you can separate them all out if you like.

 

You are correct in saying a temporary voice is needed for the A flat.

 

One quirk you will find is the matter of the dot on the A flat. You can play 
around with this as you see fit, but the voicing offsets seem fine to me.

 

The output compares favourably with the score I found on IMSLP.

 

I would recommend this style of working rather than the parallel music 
approach. One can argue that it is simpler to get voicing matters under 
control. At least, I think so.

 

You can find the standard template for piano in the MN in Section A 3.1.

 

 

Andrew
