Very good work! Just right for a beginner/intermediate student. It is a simple etude but to write a simple and good piece is not always so simple. I think that your harmonic and melodic progression is excellent. Also, when listening to your other uploads, I must say that you actually have a feeling for this, which is great.
The rhythmic structure of the piece is a nice choice. Of course, this structure has been used many times by other composers ( my first thought, when looking at your piece, went to the 21th prelude (in B-flat) of the first album of “ Das Wohltemperiete Klavier”)
Funny to say that I have also considered writing an étude using this structure (and so, apparently, has J.Santos). But I think that this is no problem at all. There are an infinitive number of new possibilities!,
Thanks a lot for uploading this little piece.
