While browsing the online Duben collection I stumbled upon a Sinfonia by Albrici with a part listed for Chitarra.
It brought to mind Lex's inquiries about specific mention/uses of the guitar as a continuo instrument. Sinfonia a 6./Primo Tono./di/Sig:r Vincenzo Albrici./1654. You can have a look here: http://www2.musik.uu.se/duben/presentationSource.php?Select_Dnr 66 On part 08 click on "Browse Part". It's standard bass clef notation with figures. -- R -- To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
