Lilypond vs. Petrucci, round 3

After my last
post
on the subject of trying to get Petrucci-like spacing out
of lilypond, someone came up with a conceptually simpler way to
get equal spacing — just tell lily to treat all the notes as if
they were quarter notes. It isn’t automated yet. For each note,
you have to tell both the value to print and the fraction of the
note value to use for
spacing, and you effectively have to put the line breaks in by hand, but it really does look a lot more the way Petrucci did
it, and less like a nineteenth century engraver who thought a
breve was a large note value instead of a short one.

So here’s what the tenor part looks like now:

And to remind you, here’s the facsimile:

Some pages are now being redirected

I have the new site up at serpentpublications.org.
Since I will no longer be maintaining the music portion of this
site, I am now redirecting the automatically generated pages to
the equivalent pages on the new site.

I’ll deal with the written pages as I get to them.

In general, the new central place for information about all the
pieces I’ve published is the
new By Composer Page.
Let me know what you think of it.

New Serpent Publications Website

It’s been a busy week, but the new Serpent Publications website is starting to be
ready for friendly eyes.

There’s still a lot of page content to be written or
transferred from the old site, and I’ll be tinkering with the look
of the pages and fixing up broken links and such in the
database, but the music is all there and can be accessed from the By Composer page.

The piece that’s a test for the new piece pages with previews
is
Douce
Memoir.
It needs some editing; someone asked for it and it was a mess, and I got it converted to current lilypond, but haven’t finished fixing the underlay.

It’s conceivable that I’ll even be ready to go live to the
world at large by Wednesday.

More about what I’ve been doing later, but let me know what you
think.

Programming again

The web application I’m trying to set up for the Serpent Publications
website is the most programming I’ve done for several years.
I made my living as a programmer for several decades, so I wasn’t
expecting it to be quite this hard to get back into it.

Part of the problem is that mysql and php aren’t what I ever did for a
living. I don’t remember the details of the vocabulary even for
what I did used to do very well, but I never knew either mysql
or PHP without a reference book.

Anyway, I was finally making progress on setting up the mysql
views this morning, and I completely forgot that I hadn’t posted
to this blog, so this is a fast one because any minute now Sunny will decide
it’s time for his walk and I’ll have to take him.

Anyway, my advice for what it’s worth, if you haven’t
programmed for a while and need to, is to go back to doing very
small things at a time. It’s generally good advice for
programming anyway — you get testability and reusability and all
kinds of good things by breaking up the job into little
pieces.

So yesterday, I wrote up a list of all the fields that should
be in the pieceinfo view of my musicpublish database.

This morning I got each of them to work individually in an
interactive environment.

Then I wrote the sql that defines the pieceinfo view, which
takes data from the piece, book, and composer tables, by way of
the Book_Pieces_Table for joining book and piece.

Another good piece of advice is to set up an interactive
environment that you’re comfortable with. The command line mysql
is pretty good, but I got farther and faster when I switched to
the emacs sql mode.

Anyway, the upshot is that I’ve got a working although minimal
CSS theme, most of the hard part of the mysql is written, so what
I mostly have to do is write some PHP (some of which I may be able
to substitute python for), and then I’ll have a subset of the
functionality that I can throw at people for testing.

I’m not really sanguine about getting the whole application
written before BEMF, but I’m
optimistic that I can get at least as much functionality as is in
the current site, with improved design for easier upgrading.

Lilypond vs Petrucci, Round II

I said in the round one of this
comparison
that I’d let you know if I got any useful
answers to my query on the lilypond list. One of the list
contributors got interested in the problem and wrote me a new
layout block that does indeed look a lot more like what Petrucci
does. You can read the gory details on the
list.

Comparing Lilypond and Petrucci

While I’m working intensely on the site redesign, you might
have to put up with the things I’m writing about it to help me
think.

Here’s a query I made on the lilypond-users
mailing list:

In general, I love the way lilypond output looks when compared with
other computer-generated sheetmusic.

I’m aware that the ideal espoused by the developers is the 19th century
hand-engraved sheet music.

I usually like the look of my lilypond output as compared with the late
sixteenth and early seventeenth century printers I usually transcribe.

I always like the look of lilypond output as compared with anyone’s
hand-written music.

But when I transcribe Petrucci from the facsimile, the spacing lilypond
does always looks clunky, especially in the parts with large
note-values.

I’ve recently figured out that the large note-values look better if you
put:


context{
Score
override SpacingSpanner #'base-shortest-duration = #(ly:make-moment 1 1)
}

in the layout block.

I believe Petrucci’s spacing is just equal spacing for every note, no
matter what its value.

Does anyone have any tricks for making lily’s output look a little more
like that?

I’m trying to redesign my website, and one idea I have is to have a
graphic in the header with a facsimile on one side and lily’s output on
the other. So it’s important that people not look at the lilypond
output and say, “Wow, that’s ugly compared to the facsimile.” Of course
one way to do that would be to use an ugly facsimile (of which there are
many), but it would be more fun to use a beautiful facsimile and also
have beautiful lilypond.

I’ll let you know if I get any useful answers.

Site Redesign Progress

I finally got started on the site redesign, so this has to be a
short one.

It’s the kind of project that every time you solve one problem,
three others pop up, so I suspect it will be at least days if not
weeks before I have it ready even for friendly perusal, let
alone to loose on the unsuspecting public.

I’m starting with the thematic wordpress
theme framework. It allegedly lets you customize almost
anything, but that turns out to be only true if you know CSS. I
learned a bit about it the last time I did site redesign, and
actually sort of liked the look of the site I did for the Boston
Recorder Society (they changed it when I stopped maintaining it,
so you can’t see it there). Anyway, I have the mechanics pretty
much the way I want them, and the look something like the old
BRS site, so now all I have to do is:

  • Write the content for the new pages, including the new
    search form.
  • Fiddle with both LaTeX and Gimp to get the banner at the top
    of the pages right.
  • Fiddle with the wordpress stuff so the sidebars and footers
    are the way I want them.

My accomplishments for yesterday included:

  • Finding where the home page on the new hosting site should go. I
    broke accessing it altogether twice yesterday afternoon trying
    to be too cute about that.
  • Setting up a test environment on my home machine. There’s
    still work to do on this, because I used the Ubuntu wordpress
    package to do it, so I have to fiddle with permissions and
    ownership and groups and maybe links before it really lets me
    work on it right. But I made substantial progress.
  • This morning before breakfast, I installed keyring and now I can do openssh to both the old
    and the new hosting sites without entering passphrases.

I was frustrated enough yesterday when I had access to the new
site broken and hadn’t yet figured out how to customize anything
in thematic that I considered just going to bed and reading
trash fiction, but I have persevered, so far.

The most inspiring story I learned in high school was in the
history of English literature book. Thomas Carlyle had spend
several years writing the history of the French Revolution, and
he gave the only copy of the manuscript to his friend Macauley
to see what he thought. Macauley’s maid (at least, she had to
take the rap) thought it was trash and put it in the fire.
Carlisle went to bed and read trashy fiction for a week and then
got up and wrote the book over again.

I admit that story has more often inspired me to go to bed and
read trashy fiction than to write the history of the French
Revolution. But it’s really true that there are times you just
shouldn’t be doing some things, and it was looking like
yesterday afternoon was the wrong time to be slaving over a hot
computer.
