Nice! Very informative; Very elegant, both in how it looks as it is 
rendered, and in the implementation: grobs classified using html 
classes, and the timings embedded in the svg.

I like the flexibility offered via the html class attributes - I can see 
how easy it would be to modify the presentation, for example to colour 
noteheads red as they played.

I like the way the video is synchronised with the audio using 
getCurrentTime of the <audio> element, so that it responds to the audio 
controls properly.

I found myself wondering if it could be made still more declarative by 
using svg animation. But I don't know how one would then get proper 
synchronisation with the audio.


But I'd still like to know how to find out when a page of a score begins :-)
