Hi,

I'm looking for pieces of Baroque music, preferably Italian around Vivaldi's time, which would have time signature changes within a movement. Has anyone come across anything like this before? Or know where i could find out?

thanks

I have a vague idea that one of his Sinfonia Concertante has it...or maybe it's a suggested change, I'll check and report back tomorrow.

If you go a lot earlier than Vivaldi, there's lots of Italian music which has shifts in time signature - Dario Castello's sonatas prima and secunda for a treble instrument - violin, soprano recorder or cornetto, for instance. But he's 1620s-ish. There is a recording of Andrew Manze playing these on a CD called Stylus Phantasticus, I think, and the sheet music is readily available too. These are single-movement sonatas, though.

Does it need to be instrumental?

Yes of course, but I'd like to find example(s) of music written in Vivaldi's time, prefarably by the man himself.
