My facebook timeline has the ad for this everytime I reload the page so their obviously spending a fortune on advertising at the moment. Having had a look at the page it seems at first pass to be interesting and I note earlier threads about some of the other Musical U offerings but not this one.
Specifically it looks like a 6 week course boosting ear training using the Kodaly method (and a bunch of bonuses too). Price with the offer is reduced from $199 to $49

Has anybody done the course and got anything good or bad to say about it please?

There’s nothing remarkable about it. All one has to do is hit the right keys at the right time and the instrument plays itself. Johann Sebastian Bach
