Once upon a time it was possible, but something changed about YouTube's embedding, so that it's no longer working. For now, the best you can do is post a link as plain text, and the forum software will automatically make it into a link.

An interesting alternatim performance. This is normal in France and is certainly a degeneration from Baroque and earlier alternatims. Once upon a time each organ 'verset' was a brief but interesting musical composition or improvisation based on the cantus firmus. Here we have nothing but a continuous blast of Cavaille-Coll reeds and rumbling 32 foot stops. Nothing at all of musical interest. It is interesting, though, that some form of alternatim practice is still normal someplace - and we have the French to thank for keeping it alive. I've even heard alternatim masses as done at Notre-Dame, Paris. This practice was once common throughout Europe since at least the XIVth century through the early XXth century when a certain pope (which one I don't recall) forbad the practice.

Love that Te Deum. It is characteristically French and the French have always gone their own way and done exactly as they pleased.
