Hello Dear Forumers. :) Very happy to write my first post.
I'm an amateur and like to study works of classical masters to see how certain things are done and among other things I also try to grasp counterpoint theory and learn about species. Recently I listened and analysed the score of Beethoven's 9th symphony's 2nd movement molto vivace and was struck how the strings are written:
So when I looked at the score I could not grasp what is going on here because sometimes for example there are parallel thirds descending between two voices when another voice go opposite direction, sometimes the rhythm is hanging on one note, change of octavesetc. You can see the strings "bricks" in the video so you'll see what I mean. I can't understand how it is written, is it note against note counterpoint with rules broken? I have a hard time to figure out which voice is written against which voice if that makes sense. :)
I also have a side question for things like Bach:
I was taught by the materials that two voices should generally be in opposite direction or oblique motion for the best effect, but this uses parallel motions almost all the time from the beginning minus the leaps on every first note in the group. Bach's ear dictated this or are there other principles behind this?
