Dear Lilypond developers and Lilypond interested in general:
I'm writing from Costa Rica. I'm a Math professor at the University of Costa
Rica. I've been working with Lilypond 2.8, editing some music for guitar, in
Mandrake 10.1 Linux. I appreciate a lot all the job you made for making
Lilypond possible, and I'm amazed for the results!! But this time, I'll like to
comment some problems I had about several topics, with its examples:
1- The "glissando" is almost invisible in the following example (first measure):
\relative{
%1
e,16( f) a d( f) a \glissando d4.
%2
d16 e,, f'' d a, f'' e4 ~ e16 f
%3
e4~ e16 f, e4~ e16 f,
%4
e4. e''16 b c b c f,-.
%5
e' b c b c e,-. e' b c b c f,-.
}
Is there a way of moving the note "d" after the glissando, so there's no doubt
about its existence?
2-I happily found a section of "Specific Instrument Notation" on the
Lilypond-manual, with a section dedicated to the guitar. There I saw the
possibility of setting "String-number indicators" for chords. I think it would
be good if the String-number indicators could be set to any note, including
melodic lines. This is an important topic in guitar. I know they can be set
also with \markup{\circle {n}}, but why not in a similar way as in chords: <a\n
b\m> ?
3-In the following fragment, there is a collision between the Text Spanner
indicator and the last note. Is there another options besides #'edge-text, to
avoid this problem?
\relative{
\textSpannerUp
\override TextSpanner #'edge-text = #'("C.V " _ "")
d8. <e,, d'' f>
\startTextSpan
<a c' e>4.
<e' e'>4.^> \> <e e'>4.^>
<e e'>4. <e e'>4. \! \stopTextSpan
}
Then, in the complete original score, there was a collision between the
extension lines of the "C.V." with the accents of the notes at the following
measures.
4-In guitar (as in other string instruments), there is the possibility of making
an "arpeggio" of two exactly notes, played in different strings. For example:
\relative{
e8. d' e
<b, b>8.\arpeggio
}
One of the "b" notes is played on the third string and the other on the second,
so the arpeggio can be made. But the Lilypond 2.8 display the following
message:
programming error: no heads for arpeggio found?
The arpeggio is working in "regular" chords, in other places of the score.
6-Is there a way of using "TextSpan" command not just with a text, for example
for an indication as "\markup{\circle{n}}, fingering, etc.?
Thanks in advance for the attention, and all the best,
Marvin Coto.
