Well, I do plan to post that next lesson very soon! I am always behind
.
You can certainly write good harmony and counterpoint; do not despair! In fact, you are quite good at both techniques and your invention demonstrates this.
But nonetheless your invention is very deficient in one major aspect of music.
Think carefully about all the elements of music and decide what your piece is most deficient in.
I have attached a "corrected" version of your invention I made in a few minutes. How did I "correct" it?
What improves its flow? I will give you one hint: although I altered some harmonies and added ornaments, neither of those are to what I am referring. This is something I tried to work on in our first exercise... but I think perhaps you did not recognize it for what it was.
All this said, it is a nice piece as you originally wrote it and you should be happy with your progress
. Also please understand that a real harpsichordist (or pianist) would make those ornaments expressive rather than annoying like Finale.
