Jan Dismas Zelenka (Oct. 16, 1679 - Dec. 23, 1745) isn't the most common name you think of when it comes to Baroque composers, but nevertheless, Zelenka was a prolific composer during that time. He was especially known for his creative harmonic inventions and counterpoint. J.S. Bach held in Zelenka in high esteem, and had some of his works copied, even using some in church services in Leipzig where he was a cantor.

Zelenka was born in Louňovice pod Blaníkem, a town southeast of Prague, in Bohemia.  The eldest of eight children, it was most likely that he received musical instruction from his father, an organist, though little is known about his early years. Later on he went to study music in Prague, and was known for his skills on the violone.

Zelenka composed his Six Trio Sonatas for 2 Oboes, Bassoon, and continuo around 1721, and today we are looking at Trio Sonata no. 6.

This work is in the sonata de chiesa form, or church sonata. (Andante, Allegro, Adagio, Allegro). The beginning starts off with the bassoon and continuo in a walking line while the oboes soar above, then snake their way down, showing just the first of many various contouring lines in the movement. Throughout the movement it's obvious how the bassoon isn't just relegated to a basic bass part, but a part that very holds it's own against the melodious oboes. The second movement is a rhythmically vigorous movement, with the oboes and bassoons weaving in and out of each other's lines and is an excellent display of Zelenka's grasp and mastery of counterpoint (the art of writing parts that are harmonically interdependent yet independent regarding rhythm and line shaping) .The third movement is as tender as the second is vigorous, and the fourth begins almost regally, with a bit of pomp, and really showcases virtuosic lines in both the oboes and bassoon. Throughout the work it's obvious that no part is particularly easy; all challenge the players with rhythmic complexities and take incredible breath stamina. The creative lines, inventive harmonies, and interplay between the parts make for a highly engaging and satisfying work!
