Well, I'm trying to get to work too! I will be leaving on the 14 to Oberlin College for their Baroque Performance Institute and will probably not be able to teach anymore after that

, though I could advise you every so often if you wish. But until then I think there is much we can do. Are you still interested in writing a full piece step by step under my guidance? Of course your sarabande turned out very nice but if your still interested in keyboard piece we could start that too. If you're tired of sarabandes it could be another suite movement.
Of those last melodies in e minor I like the first and last very much. You have captured some solemn melancholy in the first and the last is flowing (though not really in a singable style!). The two middle ones quite honestly don't work as well for me, but clearly you have put lots of effort into all of them. I would suggest for the last one that you change the first G in bar 15 to F#. That way the G isn't immediately repeated afterwards.
So about the topic of melodic curve, most of the time melodies in actual music, particularly contrapuntal music, will not be in simple arch form. But they will have a sense of direction, a sort of purpose, a well defined curve even if not a simple one.
The sort of singable melody we have worked on is only one of many sorts of melody. Especially in contrapuntal music melodies are often conceived from motives.
Let's take a look at a very nice sonata by Rosenmueller at
http://icking-music-archive.org/scor...1682/03son.pdf.
You can hear that at
Track 1 of
Ensemble Vermillian: Stolen Jewels. You will probably enjoy the recorder-gamba combination. (I recommend the rest of the Rosenmueller sonata and the Buxtehude sonata starting at
Track 18. The Biber sonata is one of the absolutely most fantastically amazing awesome sonatas ever written, but I think the intended instrument, the violin, suits it much better. You could hear that at
Track 1 of
SCD: Biber Violin Sonatas.
Track 2 of that collection is by my favorite composer. I would like to hear your thoughts on all this music if you have the time to carefully listen.)
I will post the rest of this lesson soon. I just want to keep a steady flow of information even if the exercises are still in progress

. On another note, did you ever analyze that Rameau sarabande from a while back? Because if you did I would like to see the chords and other details you may have noticed. (I'm actually learning to play some of that suite.)
