Using the LilyPond typesetting program
to publish the sonatas of Domenico Scarlatti

This is useful only for historical purposes now, as LilyPond has evolved considerably since I used it.

The sonatas of Domenico Scarlatti pose unique technical problems to a typesetter. The music is dense - many notes, close together. The original is written as if it were polyphonic, even though it mostly isn't. It ranges over the keyboard to such an extent that Scarlatti abandoned the clef-based notation of his time, and wrote parts that wander all over a pair of staves with fixed clefs. He had the fastest fingers in Europe - 1/32th notes filling a bar are routine occurrences, as are double trills and trills on the middle notes of chords. Finally, he used his hands interchangeably, anywhere on the keyboard, and intertwined, to an extent unequalled by any composer before or since.

LilyPond grew up with these rather remarkable requirements in mind (and others), and my Scarlatti edition grew up along with it. So, this note reflects an Odyssey with the LilyPond typesetting program from 1.1.13, and is an application note for it as I used it for the final sonatas (1.2.16).

The LilyPond language provides for a set of nested containers, called contexts. The Score is a piece of music. It contains a paper block and staff groups - I use PianoStaff. Each staff group contains Staffs - single lines of music. Each Staff contains Voices - sets of notes that are stemmed together. Finally, a Voice contains Threads - notes using the same head. That is:

   > > > >
 > >

Each typesetting element must be used in its proper context. The ones I use are:

LilyPond sends its output through the TeX system, where a few more layout parameters may be set. The spacing between staff groups, interscoreline, defaults to 16 pt - I prefer 8. The paper height is also set in TeX, by the geometry command; I use
which, together with the LilyPond linewidth 188 mm, permits printing on all laser printers of which I am aware using either letter or A4 paper.

These, plus the spacing parameters mentioned above, are the only means Lily currently has of adjusting the physical length of a score so that it fits neatly on a page. It has to be done manually.

Of course, what would a note like this be without WIBNI's (Wouldn't It Be Nice If...) ?

Some day ...


Scarlatti is mass production - 555 sonatas, 2000+ pages. The procedure I use is designed for that:

  1. With a sequencer program (Cubase Compact on Win3.1)
    1. play the score on a MIDI keyboard (in time with a MIDI metronome)
    2. quantize note starts and lengths (to take out my sloppy finger work) with the Cubase editor,
    3. move notes that shouldn't be stemmed together into separate channels, which become separate LilyPond voices,
    4. output a MIDI file;
  2. convert the MIDI file with midi2ly (-b is necessary except for the simplest duple-meter pieces) in Linux;
  3. merge the midi2ly output into a template, thread by thread, with a text editor (I use WordPerfect in NT);
  4. reformat with a BASIC program (lilyconv, in NT) to remove duration repeats, especially \times{}, so that each measure takes one line, convert common compound durations (such as a4~a16) to tied notes, and convert the appropriate number of sharps to flats. (Scarlatti doesn't use keys in the modern sense - this conversion is best selected manually.)
  5. create a TeX envelope file;
  6. reformat with a BASIC program (lilycln) to sequence voice and thread names, put the voice name in the measure number lines output by midi2ly, and indent each thread according to its position within its voice, so I know where I am when I do detailed editing.
  7. process to Postscript with LilyPond (in Linux);
  8. view the result (with Ghostscript in NT);
  9. correct errors, note collisions, stem directions etc. with a text editor in one half of the screen and the Ghostscript view in the other;
  10. repeat 6-9 until I think it's OK, then print (Ghostscript)
  11. play it, then (usually) return for re-edit
  12. zip and post (Cupertino in NT).

All that rebooting does sound rather messy, doesn't it?! It was. But, you see, I do a lot of heavy work in NT, where I can get reliable programs that handle things like 50 MB 24-bit colour photos, 20,000 point GIS maps, CD burning, typesetting and laser printing 100-page books, WYSIWYG word processing, HPGL, HTML, scientific graphing, fast programming of one-off research tasks, sound font creation... and do it all to modern interoperability standards. (I talk to the world, and there aren't many Unix systems out there.) Central to it all is WordPerfect, which gives me an editor with 256 hotkeys, and as many custom GUI's as I need, set up so that everything I need to do is under my fingers in a consistent way. That consistency just doesn't come using a different editor for each task, and few things are more important for speed and accuracy of computer use.

VM Ware was one option to avoid the rebooting, but the truth is I was getting tired of fighting Linux and having to beg for help from gurus every time I wanted to get something done. And so, I switched to the Windows version of Lily. It works - I recommend it.

Here are some of the templates and programs I use. I hope you get a useful idea or two from them for your own work. To convert them for use with Linux, prefix each line with "ugh"   :-)
