Introduction to BWV 169 -- Gott soll allein mein Herze haben
This week we continue Trinity season cantatas with BWV 169, the second of two works for the 18th Sunday after Trinity. Details of text, commentary, recordings, and previous discussion for this week are accessible via: http://www.bach-cantatas.com/BWV169.htm
The link to commentary by Julian [Mincham], music examples included, is especially recommended as an introduction to listening.
The BWV 169 page has convenient access to notes from the Gardiner, Koopman (notes by Christoph Wolff), Suzuki, and Leusink (and more!) CD issues, via link beneath the cover photo.
The chorale text and melody are accessible via links at the BWV 169 page. Francis Browne has recently added new commentary on the cantata texts to his interlinear translations, linked via [English 3]. We can expect these to continue, not necessarily weekly. Douglas Cowling and William Hoffman are also posting relevant to chorales and other music for the Lutheran Church Year, accessible via LCY pages.
I do not always take the time to check all links before posting. Special thanks to the folks who provide timely corrections.
