Beautifully Rendered Music Notation With HTML5 259

An anonymous reader writes "This is incredible. This guy has built a music notation engraver entirely in JavaScript, allowing for real-time music editing right in the browser. Here's a demo. The library has no external dependencies, and all the glyphs, scores, beams, ties, etc. are positioned and rendered entirely in JavaScript."

        Do you not see the "min" in the script file name? which means its been "minified", which means the whitespace has been removed, which pretty normal for JS files these days. makes the file much much smaller to ease transport across the wire, and a subtle way of confusing casual JS newbs (like your self) as a very futile attempt at security.

      I think he meant that the library has not external dependencies (and not the demo page).

      The jquery dependency is only for the the document.onload handler, and not the actual rendering code. I took out the jquery script tag, and replaced $(...) with document.onload and everything still worked.

      He's just using loading the jQuery library from Google. The jQuery library is FOSS though (and consists of that single file), he could just as easily store it on his own server and is probably using Google for convenience's sake. I suppose technically jQuery is a dependency, but it's just JavaScript itself and so many people use it that I basically consider it part of the language now.

      • At 72k for the "minified" version, it's the wrong thing to do if it's not needed. The correct way to demo that a library has no external dependencies is to create a page without anything except that library and a document.onload handler to invoke the test case.

    I currently work in the field of computer music typesetting, and can vouch for the fact that it is a hard problem - one that is considered not to amenable to being universally automated by computer.

    Achieving a rendering of very simple scores such as these is easy, but coping with anything more complex starts becoming a difficult data structures and algorithms problem really quickly, and the layout rule-set becomes increasingly complex in order to handle the myriad corner cases.

    What we see here is a great start, it demonstrates that it's possible to render music symbols in HTML canvas, but it's very far from being a complete music typesetting solution that can take an arbitrary description of a score and produces rendered output, which is the impression conveyed to many of those commenting here.

    The data model of the score in the example is generated programmatically (it takes up about 1/3 of the javascript file) and is fairly simplistic. This is an important consideration as the only sane way to create and edit scores is with a graphic editor of some kind, such as Sibelius, Finale, Notion or a bunch of open source alternatives.

    Increasingly the de-facto interchange format for these is MusicXML [recordare.com], however MusicXML is largely a semantically oriented description of the score with optional positional data rather than a presentation-oriented one. Indeed, if a presentation oriented description is what you required, you might as well use SVG to start with.

    Generally the approach one would take would be to convert the MusicXML data model into a presentation oriented one, applying layout rules as you go.

    The small amount of layout logic here is very simplistic. Things become much more difficult when multi-stave scores, paging, line-breaking and justification, slurs and so on. I'd would also suggest that whilst implementing the complex algorithms and data structures required in Javascript is certainly within the bound of possibility, it would not be easy, and wouldn't be my first choice of implementation technology.

I've been using the OSS "MuseScore" editor, and I'm perfectly happy with the layout (less so about usability).

        The layout of score conveys enormous amount of semantic information about music - for instance, the horizontal position of notes align across the staves of multiple parts if the notes start concurrently. In multi-voice music, stem direction is used to indicate which voice notes belong to, and therefore also implies phrasing. There are many other examples of this kind.

        I'll admit that it does take a trained eye to actually spot the differences in a TeX output versus something crappy from Word. But much of the improvement with TeX, though subtle, can actually facilitate reading. I don't know if those effects are really large enough to measure well, though. I notice them because I know they are there.

        Music notation is a different animal. You can usually read text at your leisure, and if you misread something the first time, you can go back and read it again. With music notation, you should be able to read it accurately in real time, and that means any little thing that you stumble over can be an annoyance to a performer. Suddenly, you feel the need to mark up the score to point out that sharp you missed, the extra beat that was obscured by poor spacing, etc.

        Obviously, standard notation applications have been producing crap layout for decades, so I suppose people have gotten used to it. But I have done a lot of work with Finale and Sibelius (for example), and I've used music typesetters that are better at spacing (e.g., Lilypond). The Lilypond output actually is easier for me to play from, even in pieces I've written or know really well. Yes, this is anecdotal evidence, but I have a lot of friends who are professional musicians that have agreed (even if they use Finale or Sibelius themselves because they are easily available and WYSIWYG). Finale and Sibelius have gotten a lot better over the past decade, but a lot of that improvement has to do with better automatic spacing algorithms.

    While I certainly applaud the effort to create a music-editing program in an HTML5 app, this is far from "beautifully rendered music notation."

    Basically, from the "demo," we can see that he's managed to map music glyphs onto staves. That's barely "music notation," and it certainly isn't "beautiful" yet. As others have pointed out, there doesn't seem to be a lot of attention paid to spacing, sizing, general layout, etc.

    I'm not saying it isn't promising, but if music notation were easy to do well, a few applications like Finale and Sibelius wouldn't have a complete lock on the professional market. Lilypond is the only good open-source alternative I know of, but it isn't WYSIWYG, and I don't know of a free WYSIWYG music notation program with high quality output, i.e., the kind that a professional musician would like to use.

    Calling this "beautifully rendered music notation" and saying this guy has a "music notation engraver" is sort of like saying that somebody who built a basic text editor that outputs plain text without formatting has created a "publishing application" that "renders beautiful typeset prose."
