OK, since this is getting serious, I'll confess to a life-long distaste for any music labelled "Scherzo", ever since a music-teacher told me it meant "a joke". Because frankly I've never come across a Scherzo that makes me laugh. Music can create a lot of emotions, it can make me happy, but laugh - no, never. My feeling was that if the average musicians idea of a joke is a typical Scherzo, then someone hasn't got out enough.
I'm not in favour of over-emotional gushing, but nor am I greatly in favour of musicians who seem to take themselves too seriously and stand in depressed rows when they're playing or singing something that's intrinsically not a gloomy piece (I'll allow gloom for Dido's lament, but Baroque music was not written as an exercise in trigonometry, and therefore can be played without an expression of painful concentration).
I suppose that what I mean is this: forced gravity is as false and off-putting as forced levity.
Here, in evidence, is a reasonable example of levity not taken to excess: a Polish university choir singing the theme from the Muppet show.
