I've been scouting around for sight reading/ear training software and have found some good stuff linked to on vocalist.org site.
The best ones so far are:

Happy Note - which gives you a melody line with increasing numbers of notes in it & you have to attempt to sing it by sight. simple but effective. Its a freebee. It also has a game which might be good for kids.

MusicBox2.7 - which does various things including melody dictation. It is a functionally limited trial version (which you are supposed to stop using when your concience tells you to) & I can't find a UK distributor though.

The best one I found though is EarMasterPro4. This is a 21 day functionally limited trial - but there is a UK distributor & it costs £50 for the full licence. It seems to do everything you'd need - and I'll probably be buying the full licence unless I find something even better in the meantime.

Just thought I'd pass on the above info.

Does anyone have any similar to add? Or any opinion on the above?
