Lilypond is written in C++ and Scheme (using Guile) and various components use 
Python. Although I am not au fait with iOS, I don’t think you would be able to 
compile and build lilypond in that environment. Lilypond is powerful and 
complex – I am fairly sure a heavyweight program such as this would be 
difficult to implement on iOS systems such as a phone. So far I have not heard 
of any iOS port of lilypond. I may be wrong!

Re: Guitar harmonics indicators

[Andrew Bernard]

Hi Tim,

Thanks. I neglected to mention, as not being totally relevant, that the piece 
if for 10 string guitar exclusively, with the extra string notes being 
indicated in the bass. Also, with my colleague, of the New Complexity School, 
for this piece the notation cannot be changed, say to use harmonic note heads 
and so on. This is a fixed requirement. As to playability, since being composed 
in 2008, the players who have done it all seem to like the notation, but then 
they are naturally specialists in modernism and new complexity, not your 
average classical guitarists I guess.

Re: Guitar harmonics indicators

Hi Andrew,

yes it is common. Pierre already pointed you to \5 (string number) and a
markup for the fret.

Besides the special case of harmonics, roman numbers are also used to
indicate a general position (German: Lage) of the left hand. In this
case the number is the fret of the index finger, other fingers then play
on higher frets. The position usually stays the same for several notes
and can be indicated by a text spanner. The following example shows this
meaning:


\version "2.19.36"

m = \relative {

  \override TextSpanner.bound-details.left.text = \markup { \small XII }
  \override TextSpanner.direction = #DOWN
  a\5\startTextSpan b\5 c\5 d\4 e1\4 \stopTextSpan
}

<<
  \new Staff { \clef "treble_8" \m }
  \new TabStaff \m
>>


Cheers,
Joram

That is real! In my classical guitar education (50 years from now) I 
just had to read and play such notes for training purposes. I never 
needed that again.


One fairly common standard is using an open diamond head to indicate the 
harmonic, but that is really only useful for octave harmonics.



I do not agree that the diamond representation is useful only for octave 
harmonics. But an open diamond indeed is exclusively used for octave 
harmonics in some natation systems. The filled diamond head is then 
usually used for the other harmonics. But it is also common to use just 
normal (eliptic) note heads with Arabic or Roman numeral to indicate 
fret number. The string number may or may not be expressed and the left 
hand fingering may or may not be expressed. Sometimes one might find a H 
or a small empty circle obove notehead or beside the fret number. All 
combinations will result in many different possible ways of notation 
really in use!


Some composer/arrangers who use this system of natural harmonic notation 
differentiate between harmonics that sound the same pitches as the 
written notes and those that produce different pitches from the written 
notes. Heitor Villa-Lobos used this type of notation, but to regret, 
there are many, many errors/mistakes in his printed sheets.


To summarise, there are many systems for notation of harmonics. The most 
used is the system of Heitor Villa-Lobos . (That is just my personal 
impression, I think it depends on the publisher that published most of 
classical guitar literature?)


At the 12th fret, the pitch of the written note and the pitch that comes 
out of the guitar are the same. At the 19th fret the harmonics sound the 
same pitch as the written pitch.


At the 7th fret, the pitch produced with a harmonic is an octave higher 
than the written note. At the 5th fret, the pitch that comes out of the 
guitar is an octave plus a fifth higher than the written note. At the 
4th fret, the pitch that comes out of the guitar is two octaves higher 
(though noticeably flatter) than the written pitch. At the 9th fret, the 
pitches that come out of the guitar are exactly the same as the 
harmonics at the 4th fret. (Will often be used for tuning a guitar or a 
bass.)

Embedding LilyPond in iOS app?

[SNIPER36]

Hello, I just came across lilypond while looking for a notation library that
I can embed into an iOS app. I would like a view in my app that shows one
bar of music notation at a time, and the lilypond file would be created
programmatically, not by the user. I read the "Inserting LilyPond output
into other programs" section, and see that I can output a png, which I could
then display in my app. I'm just not sure how to embed this capability into
the app, or if it can be done at all. Any help is appreciated. 

John

Bear in mind, though, that fairly few guitarists are used to seeing guitar 
written as if for piano.  Johnny Smith advocated that, because it allows the 
guitar to be written as it sounds, but he was almost unique.  99% of the 
relatively few guitarists who can sight read expect to see treble clef, 
transposed up an octave.  Few could play the example given.

Re: Guitar harmonics indicators

From Lilypond Manual 2.4.2 Guitar
Subchapter
Indicating harmonics and dampened notes

Special note heads can be used to indicate dampened notes or harmonics. 
Harmonics are normally further explained with a text markup.


\relative c' {
  \clef "treble_8"
  \override Staff.NoteHead.style = #'harmonic-mixed
  d^\markup { \italic { \fontsize #-2 { "harm. 12" }}} 1
}

Re: Guitar harmonics indicators

Hi Andrew,
Yes it is.
Try something like:

{
 2^\markup
 %% optional:
 %\small
 \center-column{
   %% optional:
   %\italic
   "XII"
   %% optional:
   %\fontsize #-4 \circle\number "5"
 }
}

Cheers,
Pierre

You don’t need the # here; strings in LilyPond syntax and Scheme syntax
