I woke up with this in my head this morning.

It's one of my favourite Handel arias - 'Scherza infida' from the opera Ariodante (1735), first performed by Giovanni Carestini. There's a synopsis here (although for some reason it's listed as a tenor aria). As you'd expect from a highly-emotional showpiece aria, it's wonderfully over-the-top! Here Magdalena Kožená acts it beautifully - powerfully expressive yet understated in terms of embellishments. I definitely have a bit of a vocal crush on her...

There are some free scores here, but I'm not thrilled with them. I think another trip to the State Library is in order.

Here's another take on the same aria, by Philippe Jaroussky. I love what he does with the second half! I think the key with singing this sort of music is to take things almost too far, whichever approach you choose. ;)
