Thank you for volunteering! I'd love to do it, but frankly am very hard
pressed to accomplish what's already on my schedule. Ha! Once again this
file forum comes to my rescue. I'm so pleased to be here, and of all to be
able to use and continue learning about Lilypond. What a gift this this
is...
I wrote the section about \articulate, that's why I am asking you for
a better wording, as I am not a native English speaker.
OK - I visited the Lilypond website and tried to figure out how to post
to some documentation discussion list I thought existed. That left me
confused and without options, so I'm back here. The best I can do is
offer a first draft rewrite here, and know that those better informed
than I will know what to do with it. I thank them in advance for their
assistance.
Proposed revision to Notation Reference:
[begin proposal]
*3.5.7 The Articulate script*
Use of this script changes midi output in several ways, which can result
in a more realistic sound, and also a more accurate representation of
certain aspects of the score input.
The script tries to take articulations (slurs, staccato, etc) into
account, by replacing notes that normally sound for the full duration
notated with notes composed of sound plus a small interval of silence
whose duration tries to reflect the desired articulation. It can also
optionally try to unfold trills, turns, etc., and take /rallentando/
and /accelerando/ into account.
To use the script, insert at the top of your script (after your
/\version/ statement is good) an /\include/ request:
\include "articulate.ly"
Then, in the \score section of your script, add a reference to the script:
\articulate <<
all the rest of the score...
>>
Optionally, to enable performance of abbreviations such as /trills/, and
full performance of all repeats, insert an \unfoldRepeats command,
making the snippet above
\unfoldRepeats \articulate <<
all the rest of the score...
>>
Note that for this to work correctly repeats must be explicitly
indicated in every voice which should repeat a given section.
*Known issues and warnings*
A. Unwanted alteration of the visual score
Production of an improved midi performance in this way will also yield a
score altered to represent what the midi actually sounds like, which is
not usually a desirable result. This problem may be eliminated by using
two score blocks. The following example also assigns script lines, which
would otherwise have to be repeated in both /\score/ blocks, to a
variable ("structure") which is then used in their place, to reduce
script length:
\version "2.13.51"
\include "articulate.ly"
[score scripting...]
structure = {
[repeated lines]
}
\score {
\structure
\layout {
[layout specifications...]
}
}
\score {
\unfoldRepeats \articulate \structure
\midi
}
}
B. Over-articulation of notes, for certain instruments
While the slight separation of notes in the midi output often seems to
improve the sound of music for instruments which don't normally sound
legato, such as classic guitar, it can also make other instruments, such
as organ, sound unrealistic. One approach to reducing or eliminating
this problem is to experimentally alter a single line in the
/articulate.ly/ script - here is an example of such an alteration:
#(define ac:normalFactor '(15 . 16))
[end proposal]
I hope this is helpful!
