First instalment of my mini-series on J.P. Kirnberger partly based on a beautiful manuscript volume once owned by Princess Anna Amalia of Prussia. The scores it contains are available in Auke Jongbloed's Partitura Organum series. This one is here: http://partitura.org/index.php/johann-philipp-kirnberger-jesus-meine-zuversicht/
The videos provide additional background information.
