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
<http://homepage.eircom.net/%7Egerfmcc/interval.html> and triads
(http://homepage.eircom.net/~gerfmcc/chords.html
<http://homepage.eircom.net/%7Egerfmcc/chords.html>) and minor
scales (http://homepage.eircom.net/~gerfmcc/pitchEtc2.html
<http://homepage.eircom.net/%7Egerfmcc/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.
Thanks for any help,
Gerard McConnell
Lilypond can render to PNG which would probably be good for this task.
I don't think it's the right thing for dynamic music creation though.
I'm not quite sure what you are looking to do but if you wanted to
create the music dynamically, I might render them in Lilypond, chop
them into tiny bitmaps and then render them within the Canvas, using
some custom positioning logic in Javascript.
By the way... I hope you are aware that the Javascript language has
almost nothing to do with Java?! That said, I don't know how tricky
your logic is.
Chris
