Re: Problems with polyphony (rests, dynamics, lyrics, tempo)

[Reinhold Kainhofer]

Hi Mats,
Thanks a lot for your help. I've now managed to create two songs without 
problems, but for two other pieces I have deeper needs and I'm still running 
into problems that I haven't yet been able to solve.

It seems to work fine (is there any way to suppress these warnings?). But 
there is one big problem: If you have a dotted rest (e.g. r8.), the rests 
will still be combined, but the dots are not. So the r8. rest will have two 
dots. See

Okay, so I generated the dynamics separated from the actual notes.  Now the 
problem is that the p, the fermatas, the crescendi, etc. are drawn 
immediately above the staff, even if the collide with a note!

An example of this problem can be seen in measure 4 of:

I tried it in that file ImKrapfenwaldl (measure 21, where the soprano, tenor 
and bass have "klim-p're mit den Gro-schen", while the alto has lyrics 
"klim-p're mit den letz-ten Gro-schen"). It doesn't seem to work, the error 
message is that the sopranoGroschen voice cannot be found or created. What am 
i doing wrong here?


Other problems I have with that piece:

-) The spacing of the notes is very uneven (caused by diffferent lengths of 
the lyrics). See e.g. measure 46, which contains 4 eigth-notes, which are 
spaced very uneven. 

-) The whole piece is space too narrow for my taste. Is there any way to 
increase the horizontal spacing of the whole document.

-) the dot of dotted notes is too far away from the note and too near to the 
next note. See e.g. measure 67 of ImKrapfenwaldl.pdf

-) What is the correct way to type-set a piece with a main part, a trio, a da 
capo and a final coda? In particular, I need line breaks exactly where the 
trio and the coda begins, and I also need the correct repetitions in the midi 
file.

-) The way described in 
http://lilypond.org/doc/v2.4/Documentation/user/out-www/lilypond/Rehearsal-marks.html#Rehearsal-marks
to put a coda (or fermata) sign above a bar line doesn't work for me. The bar 
line after measure 55 should have a fermata sign (as specified in the 
tempos). (Actually I want a coda there, but since the example given in the 
docu doesn't work, I didn't try to find the coda sign.)

-) How can I make a line break inside a measure. In particular, in measure 56 
the Trio begins inside the staff. How can I for a page break before the r8 
break?

-) In measures 78 and 82, is there any way I can add an underscore until the 
end of the measure (similar to a melisma, only that there is only one note in 
that measure).

-) The whole measure rests in the last system are not centered inside the 
measure (measures 109-111 and 115.

-) The fermatas on the rests in the last system are not drawn above the rests. 
What am I doing wrong here?



The same problems (spacing much too tight for easy reading, whole measure 
rests not centered, main/trio/D.C./coda structure, coda sign on the staff) 
also appear in 
http://www.fam.tuwien.ac.at/~reinhold/lyprobs/TritschTratsch.pdf
http://www.fam.tuwien.ac.at/~reinhold/lyprobs/TritschTratsch.ly

-) The additional problem I have there is then the key changes from a to e 
(three sharps to four sharps), one would usually just write four sharp signs 
for the new key. But lilypond first completely cancels the a key (three 
natural signs), only to add four sharp signs immediately afterwards. See line 
19 of TritschTratsch.pdf. How can I prevent this and force lilypond to skip 
the natural signs.

-) In TritschTratsch.ly there is not one voice where I can assign the lyrics, 
because every now and then only one voice keeps singing, all others are 
quiet. So I tried the trick to change the associated voice with 
 \set associatedVoice = basses
But that doesn't work at all. If I uncomment all these lines in the lyrics, no 
lyrics are printed at all after the first \set associatedVoice. For an 
example see:
http://www.fam.tuwien.ac.at/~reinhold/lyprobs/TritschTratschAssociatedVoice.pdf

Thanks a lot for all your help.

Cheers,
Reinhold
