Music typesetting isn't as easy as it looks (Score:5, Insightful)
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'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.

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.

*Real* typography geeks say Knuth got everything wrong.
Sure we do. We know Knuth was crazy to talk about paragraph-based hyphenation and justification, and it is madness that the Knuth-Plass algorithm remains the gold standard in H&J today and something that only TeX itself, InDesign, and a few high-end specialist packages can match even now. We hate all those fiddly thin spaces that you have to type manually, too; we’d much rather just have our adjacent quotation marks and superscripts clashing.
Speaking of superscripts, we know Knuth’s font design skills were appalling as well. Anyone could design a system of fonts that was still clearly legible when used to typeset mathematics with sub-subscripts at 4/5pt on the one hand, yet provided extensible brackets surrounding multi-line expressions without looking overly large on the other. We know this from the vast number of font families available from the world’s leading type foundries today that do the job, and the way mathematical journals have given up on TeX because modern fonts provide a much wider range of mathematical symbols that are still clearly distinguishable from any Latin or Greek glyphs that may appear nearby.
Maybe TeX was just behind the times, though. After all, in an era when TeX could only typeset a variety of proportional fonts with intelligent hyphentation, ligatures and correct punctuation, at a useful range of sizes, in a way that could survive photocopying a research paper and still be legible, the world’s serious typographers were probably already using word processors that could render a fixed size, monospaced font on their dot matrix printer with underlining!
TeX’s handling of fonts is archaic by modern standards, of course, though updates like XeTeX do a much better job when it comes to things like OpenType and Unicode. However, in fairness, Knuth developed TeX many years ago, at a time before these modern standards were a glint in their metaphorical parents’ eyes. I think it’s rather unfair to criticise on this basis, and much of what he did has set the standard for three decades.
Getting back on topic, if the person or people behind the tool we’re discussing can do half the job for musical notation that Knuth did for mathematics, it will be a very fine achievement indeed. As with mathematics, it is relatively easy to scribble musical symbols in a way that is technically correct, but rendering music in a way that remains clear and effective even when read at speed in large volumes is quite a different thing. Nitpicking about some of the typography in an early demo seems a little unfair, given the already high standard of the overall rendering.
