The best experience I had with online playing was with ninjam:
https://www.cockos.com/ninjam/

It's an open protocol and free software implementation of a server
and a few clients (text, console, gui) for online jamming.

The idea is that everyone play on a tick (Beats Per Minute) and
everyone is ensured to always hear some previous recording of
anyone else on a defined cycle/interval (Beats Per Interval).

Depending on how the server is configured (easy to setup) the
BPM and BPI values can be fixed or driven by votes. Protocol
includes a chat and is text based for commands (like: "!vote bpm 60").

Some public servers do exist, which also support automatic recording
of resulting sessions ("autosong", the software doing this, is also
part of the main ninjam source code repository).

See http://ninbot.com/pubservers for a community curated list of
public servers. See top-level page for recordings of jams played
on ninbot.com servers.

An easy to setup QT based free software client is http://jamtaba.com

Thanks, the \scale hint was very useful.
Doing it before the \score block isn't convenient as I'd have
to repeat the insertion in every book. Using markup
in header seems ok for now, I'd only need some proper alignment,
as I'm currently doing this wild thing:

  piece = \markup {
\italic "  With a beat  "
\scale #(cons 0.8 0.8)
\score {
  ...
}
  }

The spaces I'm using to move the tiny score more or less at
the center of the sheet, but is fragile. Also the "With a beat"
text position is too high, it would be nice to have better
control over it.

What happens if I prepend that staff to the rest of the lead sheet,
which starts with:

  leadSheet = {
<<
  \new ChordNames {
\harmony
  }
  .

Is that the new Staff continues instead of being interrupted.
I'd want it completely detached instead (and smaller).
Nice one, line-count, but I think I can deal with full staff as well.

Yes, but I would ideally use an \override so to keep the existing
definition of my leadSheet. Here's what I have:

  \book {
\bookOutputSuffix "G"
\header { subtitle = "(G)" }
\score {
  \transpose c b
  \leadSheet
}
  }

  \book {
\bookOutputSuffix "F"
\header { subtitle = "(F)" }
\score {
  \transpose c a
  \leadSheet
}
  }

And what I'd like to add is something like this:

  \book {
\bookOutputSuffix "F-ita"
\header { subtitle = "(F)" }
\italianChords % <-- but doesn't work here
\score {
  \transpose c a
  \leadSheet
}
  }

Or simply create a different "book" for the midi, and only include
the voices you want... I often do this also because I want to
\unfoldRepeats and maybe add a \tripletFeel and most significantly
because I'm using transposed instruments which then need to be
transposed for the sake of MIDI output but not for reading...

Would setting volume to zero be ok for your use case ? If so, try
something like the following:

\new Staff \with {
  midiInstrument = "muted trumpet"
  midiMinimumVolume = #0.0
  midiMaximumVolume = #0.0

Ok, sorry. The problem was this block:

  \layout {
\context { \Voice
  \consists "Ambitus_engraver"
}
  }

It looks like using an "Ambitus_engraver" with a \partcombine
results in that warning. I tried a \remove "Ambitus_engraver"
in the part-combined score but didn't work so I ended up moving
the \consist in each score in which I wanted the Ambitus engraver.

Actually, I'm thinking I'd build a database of available ranges
for instruments and players / singers, so that when a score
is intended for playing by known people I'd just reference
their names in the score...

The thing is I'm writing multiple scores with the same parts
replicated (some with all 3 voices, some with just 2 voices)
so I'd like to avoid the duplication of ranges. A range is
specific to an instrument so I'd like to specify that in the

Thanks, "ambitus" works great for a start.
Next step would be automatic checking if the ambitus is within
an instrument capability, which the coloring hint by Aaron should
help with, if I handle to make it work :)

I did not transpose eeses, but ees.

Indeed I do get that warning, but I was not transposing eeses ??
Where does 'eeses' come from ?

Yup, this one fixes the warning and the weird rendering.
Still uses double-alterations (double-sharps) but that's a
separate issue (does lilypond have any support to automatically
simpmlify those notes and/or chords?).

m7.5- transposed to sus#4 b3 ??

[Sandro Santilli]

I transcribed an A major song with this chords snippet:

  ees:m7.5- | aes:7 | aes:m7.5- | des:7 |

When transposing it to Eb major it is rendered as:

  Bbbø | Ebb7 | Ebb7sus#4 b3 | Abb7

I don't understand why the third chord (m7.5-)
gets rendered as a "7sus#4 b3" chord, very hard
to read ...

Ideally I'd also like to avoid the double flats,
but what strikes me is the "sus#4 b3" part, is it
a bug ? I'm using GNU LilyPond 2.18.2 and the
.ly file has a \version "2.18.2" header.

I don't know how Google, Dropbox or iCloud work but NextCloud

Thanks, but that would double the size of my sheet, which would then
hardly fit a single A4 page. Rather I was thinking it could be nice
to print the notes of the melody of a very bright gray so that I can

Another aspect is that you may want to just instruct the player to
do a glissando up or down to unspecified pitch for the time it is
otherwise represented as rests (with glissando sign possibly
overlapping the rests)

Great, I didn't know about scaled durations! Thank you !

It's almost exactly the same as the original,
but in the original the glissando drawing ends on the bar,
while using this code it ends in the hidden note which
is still a bit before the bar, is that what the X-extent
is aimed at fixing ?

Thanks, this also worked, although the X-offset tweak here
results in a segmentation fault with GNU LilyPond 2.18.2

Here's the snippet:

  \context Voice = "main"

\tweak X-offset #2

NOTE: it doesn't segfault if I uncomment \hideNotes, but
since the X-offset seems to have NO effect I wanted to see
those notes...

Open glissando

[Sandro Santilli]

I'm trying to emulate the output in the attached image, but failing to
do so. It is basically a glissando to an unspecified note (hidden?)
during an otherwise rest period of time.

What I tried:


\once \override Glissando #'style = #'zigzag
e4
\glissando
r4 r2 

But the glissando symbol does NOT come out.
It would if I replaced the first r4 with an actual note,
but I still do want the rest printed...

Thank you but will keep what I have as far as it keeps working.

Rather, now that I have everything hidden there's still an issue
I have with placement: the chords, on some lines (not all) are stil
way too distance from the staff, as if some (now invisible) element
is taking space. Is there maybe another way to simplify this task of

Turn lead sheet into a blank staff

[Sandro Santilli]

I'm producing lead sheets with lyrics, melody and chords
and would like to extract from them som blank sheets with
just lyrics and chords so that players can take their notes
onto (for solos or arrangements).

My first attempt has been with using \hideNotes but that one
still keeps some elements (courtesy accidentals, ties, slurs,
tuplet indications, fermata sign).

I'm trying with a custom \hide command, defined as follows:

  hide = {
\override NoteHead #'transparent = ##t
\override Stem #'transparent = ##t
\override TupletBracket #'bracket-visibility = ##f
\override TupletNumber #'stencil = ##f
\override Accidental #'transparent = ##t
\override Tie #'transparent = ##t
\override Slur #'transparent = ##t
\override Dots #'transparent = ##t
\override Staff.LedgerLineSpanner #'transparent = ##t
\override Beam #'transparent = ##t
\override Rest #'transparent = ##t
  }

but with it I'm still having fermata and courtesy accidentals.
Idea how to override them to be also transparent ?

To be honest I still find that syntax hard to understand.
Replace the 3  with A B and C, how would the
above code render those chords ?

I'm guessing it would be:

A ( B C )

But if that's the case, what is the initial \parenthesize for ?

Note I used code found in 
http://lists.gnu.org/archive/html/lilypond-user/2016-10/msg00574.html
which has similar hard-to-understand syntax, I used as such:

| g2:6 \leftParen bes2:dim5 |
a4:m7 \rightParen d2:7

Guess how it is rendered ?
For obscure reason, the right paren goes _after_
the d2:7 (which is what I want, but looks weird
in the source code).

Please note: I love the lilypond and even more the _community_ around
it, so don't take my observations as destructive as they really don't
want to be :)

Setting staff size for a single book

[Sandro Santilli]

According to the manual [1] you can use #(set-global-staff-size 14)
in a book block, but when I try (using lilypond 2.18.2) the output
does not change. Example:

  \version "2.18.2"
  \book {
#(set-global-staff-size 48)
\header { instrument = "Bass" }
\score {
  \new Staff { \absolute c' }
}
  }

Moving the #(set-global-staff-size 48) line *outside*
of the `\book` block works fine. Is it a bug in the manual
or in the code ?

Here's a minimal version:

  bass = \relative c' { e8 r8 r4 }
  aligner = \relative { c4 c }
  words = \lyricmode { la la }

See on lilybin: http://lilybin.com/tnik8y/1

Commenting out the NullVoice line results in rests being where they
should be. Setting \version to "2.18.2" makes no difference.

aligning lyrics to hidden notes

I've been trying for some time now to align lyrics
to an hidden melody but when I try that all the rests
end up attached to the bottom line of the pentagram,
which looks like a bug in lilypond itself, can anyone
see if that's the case (a bug) or I'm doing something
wrong ?

Here's the .ly file:
http://strk.kbt.io/tmp/quizas-broken-basspart.ly

This is a summary of offending section (look for
"bassPart" in the .ly above for the actual section):

bassPart = {
<<

  \new Staff {
<<

% UNCOMMENTING THE LINE BELOW
% MOVES ALL RESTS TO THE BOTTOM !!
%\new NullVoice = "vocal" { \melody }

\new Voice = "bass" { \bassline }
>>
  }

  %\new Lyrics \lyricsto "vocal" \words_line_one
>>
}

I cannot attach "words_line_one" to "vocal" NullVoice
unless I define it...

Can anyone help me making my bass player aware of lyrics ? :)

Thanks in advance !
