Er... WAV, how do you define an 'English' tenor recorder? Given that the recorder is generally supposed to have originated in central Europe, then developed from the Renaissance to the Baroque version before entering wider use in England and the USA? I'd be interested in your research on this, as my brief enquiry suggests that the recorder isn't really an English instrument at all, depite the fact that you play one.
I look forward to your reply, since you ducked my last question on another thread.
