Google video and You Tube contain thousands of amateur and professional performances of songs from the classical, opera and operetta repertoires along with huge selections of choir videos.

It's great that such a huge haul of performance is available for free, but you can easily lose many precious hours looking for the really good ones. We've created a section in the site dedicated to bringing you some of the the best: You'll find channels dedicated to opera, operetta, music hall, choral music, and masterclasses.

Tune in today, and if you find something that you think could be included, please let us know.
