My French ensemble performs often at 370, this includes specially made keyboards, winds and strings, plus large lutes at 370, which can be considered "french pitch" along with "super low" pitch of ~340. Good evidence for both pitches from historical keyboard instruments, but other pitches must have been used, such as 392, 408, 399, 411, 430, etc.
Free listen: http://magnatune.com/artists/albums/orinda-airs/hifi_play As a starting point for French baroque lute, on a "French Frey", 399 or 400 is a very good choice. I often find 415 a bit too high, and 392 a bit tubby due to the relatively small scale. An amusing pitch fact-- Most HIP classical music is performed at 430, higher than 415, even though Mozart's tuning fork was 2 cents lower than Handel's fork. dt To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
