-Hello, everyone, and welcome to the EmacsConf. I am Jonathan. In this
-talk, I'm going to demonstrate ways of producing sheet music in Emacs
-using Lilypond, and maybe also convince you to use Emacs for writing
-your scores. I'll start with an overview of the syntax for those who
-are new to using text-based notation as a shallow dive into the deep
-pond of lilies and Lilypond, and move on to showcase some of its
-functionalities using Org Mode and lilypond-mode. One disclaimer,
-however: I am not a Lilypond developer. 
-
-(00:40) So what is Lilypond? Lilypond is a file format and music engraving
-system for producing high-quality sheet music. It translates textual
-representations of music to graphical objects. It's similar to LaTeX
-in that its input format describes the visual layouts of the score,
-using commands to define musical expressions. Commands begin with a
-backslash. For example, the formatter command, as shown on the left,
-yields its graphical equivalents on the right, the fermata symbol over
-the low B and so on and so forth. It's also fully extensible, like
-Emacs, allowing users to extend and override Lilypond's
-functionalities using the Scheme scripting language. It can be used
-for early and contemporary music tablature, vocal music lead sheets,
-and so on. Above all, it works with Emacs. In fact, Lilypond ships
-with Emacs Lisp libraries, including a major mode for editing Lilypond
-files.
-
-(01:47) So the input files are similar to source files. They contain
-expressions formed with curly braces, comments that start with the
-percent sign, and the code is indented. Notes are entered using
-lowercase letters, and rests with the letter r. In this case, the
-lowercase r or r4 is the equivalence of a crotchet or quarter note
-rest. Durations are entered using numbers and dots after the note
-name. If you do not specify one, the previous duration is used. You
-can also tie notes together using the tilde symbol (~). In fact, you
-can input chords, lyrics, embellishments, and a lot more. I encourage
-you to read the manual for more information. Now let's switch to a
-terminal window. With Lilypond installed, let's create a test file
-with the extension .ly and open it in Emacs. 
-
-(02:50) At the top of the file is the version statement, which tells Lilypond
-which version to use when compiling the file. Here I'm using version
-2.20.0. I've added the clef and time signature. Let's add some notes.
-I'm going to close this now and compile the file by running lilypond
-followed by the file name. So now let's view the output. Okay. 
-
-(03:27) So here's a more complex example for randomizing note sequences. The
-idea is to create new reading materials each time the code blocks are
-evaluated. As usual, we begin with a header. I've added the title and
-composer. Then we add the note sequences to use in the composition. In
-this case, sn is a note name just like a b c d and so on, and stands
-for snare drum, the percussion instruments. Now here's a function
-that's going to shuffle the notes in the table. Finally, we expand the
-notes inside the Lilypond source block. So whatever the function
-returns is expanded inside the drums block. Now let's press C-c C-c to
-view the results. Okay. And if I run this again, it should create a
-new composition. Great. You can also audition a piece using the midi
-command, which creates a midi file of the score. 
-
-(04:34) Note also that the ob library-- sorry, the ob-lilypond library comes
-with two modes. The one I'm using now is called arrange mode and is
-useful for assembling complete scores. The basic mode on the other
-hand allows you to mix text and music by embedding Lilypond snippets
-and export them using typical Org Mode commands. 
-
-(05:00) Now to demonstrate the basic mode in action. I'm going to export this
-document to a PDF file. In this case, the :file header argument is
-required, so you have to provide one and include the file name. Again,
-you can run the code and view the results. Here it is. So now let's
-export this to a PDF file. And here it is, what it generates. 
-
-(05:39) Now I'm going to show you the workflow I used to produce music books
-in Emacs, combining Lilypond and LaTeX for a perfect marriage. I begin
-by sketching the first draft of the manuscript using pencil and paper.
-Then I move to Emacs to input the notes in a git repository. This is a
-typical source file. It begins with a stylesheet where I set variables
-and layout settings, although in general, there's no need for tweaking
-the layout unless you have specific requirements to do so. The easiest
-way to compile the file from Emacs is by pressing C-c C-l, so let's do
-this now, and the compilation buffer will tell you if there were any
-errors in the file. Now to automate the process of compiling several
-files and building the PDF, I use GNU Make, so all I have to do is
-open the shell and run the make command. Don't worry, I'll provide a
-link to the source code on the last slide. 
-
-(06:41) As I moved forward with the project, I found at least two things
-missing. One, I had no access to a metronome, at least not from the
-editor, so I built one for casual use and made it available in the
-MELPA repository. I also missed bar numbers in the source file. This
-is useful when going back and forth between input and output files
-without getting lost. So I wrote a command for toggling bar numbers,
-which I hope you can see on the left. Also, some expressions are
-difficult or slow to write on the keyboard-- accents and tuplets, for
-example--so I use template expansion extensively for this purpose,
-mainly yasnippet. 
-
-(07:23) So what do I think? Well, I think Lilypond can be a
-sharp paradigm shift for people used to GUI alternatives, but the
-results are impressive. You don't have to dive too deeply to start
-using Lilypond. Likewise, the ability to extend the software, I think,
-is especially appealing for music professionals, enthusiasts,
-composers, and the academic community: for example, allowing users to
-create alternative notation systems required in non-Western music
-traditions and other non-conventional requirements. Also, Lilypond and
-Emacs both have extensive and well-written manuals and active
-communities of users. But if you're still not sure where to start and
-when to wedge your feet in the deep but warm pond of lilies, Lilypond,
-and Lilypond users, I invite you to contribute to my Lilypond
-projects, which you can do so from the links on the screen. So, thank
-you all. I look forward to your comments, and I hope you enjoy the
-rest of the conference.
