You already know I love Mendelssohn’s motets. His Sechs Sprüche for various occasions in the liturgical calendar are short pieces for 8-part choir. I love them for lots of reasons, not least the recurrent use of my second-favorite German word “frohlocken.” (My very favorite is “Wonne”. I know you were wondering.) This video has good notes, with translations and links to the other five (of which my very favorite is Am Neujahrstage, in case you were wondering).

I could swear I’ve heard this somewhere recently…
Mendelssohn is also the composer of the most commonly performed string octet in the classical repertoire. His music is a real celebration of pure classical era form.
Kristine: Among your various wanderings in classical music, do you do much Bach? Personally, I am a huge Bach fan. A while back the set of the complete works of Bach, a set of 155 CDs, became available on Amazon.com, and I snatched it up. I read all 155 CDs into my computer, and then downloaded into my iPhone. I have now listened to everything at least twice.
I have many favorites among the Bach works, but I particularly like the cantatas and choral works. In my view, the Bach Mass in B Minor deserves the title, given by some critics, as the greatest single piece of music in the classical repertoire. I also like Cantatas #29, 51, 78, 102, 160 and a few others
