Arcangelo Corelli was a virtuoso violinist and wrote almost exclusively solo, chamber, and concertos. His violin playing was the most famous for the time, and he was unusually strict in his teaching.
The trio sonata Op. 3 No. 10 is a very short piece. Trio sonatas were typically written for two violins and continuo (cello and keyboard). The four movements are slow-fast-slow-fast. In this work, they are performed attacca. Being a work of the middle baroque, this piece features upper voices heavily, using the lower as harmony. In the second movement a lot of imitation and sequencing is heard and the continuo voices play a very active role. Despite it being classified as a sonata da chiesa (church sonata), it was not necessarily performed in religious ceremonies. It was not labeled as such for a long time after its publication.
Another composer of instrumental music was Georg Muffat. In the passacaglia movement of Armonico Tributo, the harmonic line is introduced by the soloists, then tutti comes in. The soloists play a melody and the rest of the ensemble imitates. Corelli places a bit more emphasis on the lyrical aspects of the melody than Muffat. Even though it is a smaller ensemble, Corelli uses much more harmonic range than Muffat.
I haven't played much of Corelli's works, but they have a lot of interesting melodies. I was kind of surprised by how short this one is. All of his ideas are very clear and he makes good use of the instruments. He makes much more use out of the bass lines than other composers such as Johann Pachelbel who is infamous in the cellist's world solely because of his Canon in D. It is basically the worst piece ever written.
