Hello,
About 10 years ago I wrote some Java applets which allow a user to test their understanding of intervals (
http://homepage.eircom.net/~gerfmcc/interval.html and triads (
http://homepage.eircom.net/~gerfmcc/chords.html) and minor scales (
http://homepage.eircom.net/~gerfmcc/pitchEtc2.html). They work well, but it seems that Java applets are now no longer the best way to make programs available on web pages. It seems that the HTML5 canvas is most common now. I'm not an experienced programmer but I think the logic for generating the tests should be easy enough to transpose from java to _javascript_, however for display I'm wondering what a reasonably simple way to transform the note data into music notation is. I used transparent .gifs for the original programs and shifted them into place, but I suspect that Lilypond or something similar would be better. No doubt people here have worked on this sort of problem before, so any advice would be greatly appreciated.
