Re: Assistance to Create a Recipe for 41-EDO and "Kite Guitar" Tablature

[Devin Ulibarri]

Hi,

Unfortunately, I do not really have the skills to put together a recipe
myself from the templates available (emphasis on "I do not have the
skills").

If others who are interested, who have the skills, would like to take
this on, I am happy to advise and introduce to the Kite Guitar team, who
are a great team of artists and leaders of various good causes.

Best,
Devin

Is this spam, because it looks like a spam message.
It has no context in any lilypond-related discussions
It also looks to be proprietary, which is no fun at all

Hi,

I am not going to bump this too many more times, but is anyone
interested in being a mentor for GSoC for our project.

As a sample, you might be asked for your advice on a question such as:

approximate with powers of 2 ???

...you would give your advise on the best solution and the student's job
would be to implement it. If they ever got into any trouble, then Walter
Bender, our lead programmer would help them with the technical coding.

Hope everyone is doing well!

I will revise it based on your advice--especially since the
documentation really is a by-product for this project (but a really

Any interest in participating in GSoC for SugarLabs project that utilizes lilypond?

[Devin Ulibarri]

Hi,

I have been working together with the SugarLabs team to create a visual
programming language for music called Music Blocks (MB). Users code with
blocks (like Scratch), and they can also export to lilypond code.
SugarLabs is participating again in Google Summer of Code (GSoC) and we
would love to have another person on board as a mentor (or a candidate,
if any are reading this message).

It would be great to have another person involved as a mentor to help
inform the kind of lilypond code we are generating with our program. No
one here is particularly knowledgeable with Lilypond. We just read the
docs and create something that works well enough. We think that having
another, more knowledgeable, person would be very helpful for the summer.

Links: The development version is at walterbender.github.io/musicblocks,
but a version that can generate PDF using lilypond software on the
server is available at https://homegrownapps.tk/musicblocks/

Short instructions on Lilypond generation with MB is located at
https://github.com/walterbender/musicblocks/tree/master/guide#BEYOND-MUSIC-BLOCKS

This is the Google Summer of Code description:
(Originally Published at
https://wiki.sugarlabs.org/go/Summer_of_Code/2018#Project_Ideas)
Brief explanation
Music Blocks is capable of exporting Lilypond code of which general
instructions can be found here in the Music Blocks guide and its source
code can be found here. We would like to 1) document how the Music
Blocks source code works for current and future developers to learn and
benefit from, 2) project manage this portion of Music Blocks development
(e.g. "what works" and "what needs to be done". An example of a draft of
a simple type of this analysis exists for you to start from.), and 3)
improve existing code where needed and implement needed features.
Expected results
Detailed documentation created for developer audience that details
how Music Blocks exports to Lilypond; documentation to help manage what
needs to be completed; and implement and improve lilypond export features.
Knowledge prerequisites
Literacy in reading music; functional knowledge of Lilypond code
(some of your own scores would be nice); Organizational and Project
Management Skills; JavaScript

If you are interested, please let me know.

Thanks!

This is exactly what I am looking for! :)

I will play around with this a little bit, but this looks sufficient enough.

Thanks, this is helpful.

If possible, I would like some more information about how to tweak the
output.

* Is it possible to make the space within the circle opaque, but without
hiding the number (just hiding the tab line)? If so, how is this done?

(I could do this in Inkscape, but would rather automate it if possible)

Is there a way to circle around tab numbers?

[Devin Ulibarri]

Hi all,

I see that there is a way to circle around note heads, but I would like
to circle around fret numbers. Ultimately, I would like the string line
to be hidden from the space within the circle as well to emphasize the
number. I want to use this for pedagogical reasons. (If this description
needs further explanation, please let me know)

I see this code for the note heads:

http://lilypond.org/doc/v2.19/Documentation/snippets/editorial-annotations#editorial-annotations-drawing-circles-around-note-heads

circle =
\once \override NoteHead.stencil = #(lambda (grob)
(let* ((note (ly:note-head::print grob))
   (combo-stencil (ly:stencil-add
   note
   (circle-stencil note 0.1 0.8
  (ly:make-stencil (ly:stencil-expr combo-stencil)
(ly:stencil-extent note X)
(ly:stencil-extent note Y

{ \circle c'' }

I do not really understand this level of lilypond code very well, but I
suspect with some tweaks it could do what I need. Is anyone on this list
able to help? I would appreciate it.

Thanks,
Devin

Please add MusicBlocks to "Programs that export to Lilypond"

[Devin Ulibarri]

Hello,

Music Blocks is a visual programming language for music developed by
Walter Bender (SugarLabs), myself, and many kids around the globe.

It exports to Lilypond, and Lilypond export has been a priority for us.

We noticed this page for "Other programs that can export LilyPond code":
http://lilypond.org/easier-editing.html

Would someone mind to add Music Blocks to this page, please?

Our website/blog is at musicblocks.net
Software is at https://walterbender.github.io/musicblocks/ and code is
publicly available at https://github.com/walterbender/musicblocks

Thanks,
Devin

Even in the case that a company/group unintentionally uses the same
branding (name, logo, etc) as an existing organization/company/product,
it still benefits the greater public if steps are taken to avoid overlap
and confusion with regard to said branding.

You are right, I was a little sloppy to write "Apple" specifically. In

So, no one has put in for a trademark for Lilypond?

Software can be free/libre (open source) and still have trademark.

Obtaining a trademark for free software is not a bad idea. It protects
users from potential confusion (imagine if anyone could copy any
branding they wished--how would you know you were using a brand you
trust?). Proprietary software is unethical because it restricts its
users. However because trademark protects users and not proprietors I
would not consider it unethical.

GNOME, for example, takes actions to protect its trademarked logo and
name. Here are some examples:
unitarypatent.com/gnome-trademark-infringement/
https://yro.slashdot.org/story/14/11/11/1331233/gnome-project-seeks-donations-for-trademark-battle-with-groupon

Other info from there website:
https://wiki.gnome.org/FoundationBoard/Resources/LicensingAgreement
https://www.gnome.org/logo-and-trademarks/

...having trouble finding a published reason for the rationale, but what
I have read was convincing.

Well, I guess there is a "good, bad, and ugly" according to
https://www.theguardian.com/technology/2013/apr/29/trademarks-good-bad-ugly

At any rate, just watch out, if Apple continually tries to advance into
imitating free/libre branding in an attempt to push it out of the market
completely, then that would be a problem for all of us.

Re: Apple stealing "Lily"

This stupid app will surely die, but it is worth lilypond being on guard
with regard to trademark (which has a separate purpose from copyright
and is pretty helpful to protect users from mistaking different brands
for the same).

Really it should say:

Should you Download It?

No, because it is proprietary and is therefore an attack on your
freedom. As an aside, it also looks to be mind-numbingly stupid.

Questions:
1) Would you be willing to publish an article about how Music Blocks (a
visual coding language for music. Homepage at
https://www.musicblocks.net) software generates lilypond code and how
one can use Music Blocks software as an entry point to lilypond?

2) Would you be willing to publish articles created by High School
students participating in Google Code-in (GCI)? I could draft a task and
we could have some kids write about their experience learning Lilypond
from Music Blocks. Of course, you would still have the final say as to
whether or not the blog posts would meet your standards and be published.

Otherwise, I could write something, but the above options would be fun
and the idea is off the table in a few weeks as the GCI contest closes
in mid-January.

Best,
Devin

Stem for French Lute Tablature (Dowland)?

[Devin Ulibarri]

Hello,

In French Lute tablature (e.g. music of Dowland), the rhythm is:

1. notated as stems above the staff.
2. All the voices are truncated into one (example: if there is quarter
notes in top voice and half notes in bottom, they would all be notated
as quarter notes)
3. The flags are "double" what modern notation uses, so a quarter note
has one flag, eighth note has two flags, etc. Half notes have a kind of
very, very short flag to the left.
4. Stems are only indicated when there is a change in rhythmic value. If
there is a succession of the same rhythmic value, for example, only the
first note will be stemmed until there is a change (e.g. from eighth to
quarter, or eighth to half note, etc.)

This is a decent example: http://www.guitarandlute.com/tab.gif

And this is the file that I am working on:
https://github.com/pikurasa/MutopiaProject/blob/Dowland-Fantasie-7-Variatie-Robert-Dowland/ftp/DowlandJ/Lute/Fantasies/001/A-Fantasie-1-Robert-two-staves.ly

Does anyone know how to indicate this for the tab staff? Is there a
stock command that does this or a hack?

And if this feature does not exist, then where is the best place to
request it?

Thank you,
Devin

Hi,

So I am new to this list.

I saw this email and thought that I might contribute.

However, I cannot find donation location on the Lilypond site:

Where should I go?

P.S. It would behoove you to put a donate button at least on the site I 
give above. Maybe at the bottom of emails, too.

I've taken a look at my last bank report.  In the last month I received:

1 donation of 200 EUR
1 donation of 100 EUR
2 donations of 25 EUR each.

That's it (and honestly, the two large donations are embarrassing as
they are by people who have done more than I ever did on LilyPond and
who are helping people more on lists and forums than I do,
respectively).  That does not even cover my rent, let alone medical
insurance, food, repairs, clothes or other stuff.  Let alone pension
funds or similar luxuries.  I'm currently bleeding about 800EUR per
month for working on LilyPond.

What has happened in the last month?

Well, 48 commits does not look like much, but I implemented
functionality to attach to slurs to single notes in a chord in that time
(important for tablature and piano music), designed and implemented an
interface for working with multiple slurs per Voice, fixed several bugs,
made c:5 in chord mode a power chord rather than equivalent to c major,
created several low-level functions for manipulating graphical object
properties like \offset does, removed a hard-to-understand internal
object called a "simple closure" and prepared for more simplifications.

I will likely work several more months on those internals and if the
situation has not improved by then, call it quits.

I thank all those who have supported me for this long.
