Absolute baroque style.
It's a pity we cannot see the score...
I like it, there's a beatiful middle section (1:10....).
What I'm not sure of is the tremolando in an organ (they seem very long sometimes). I think it's more typycal in the harpsichord.
It's very romantic with some sparks of "modernity".
It's surprising that all the piece long is written in a very "marcato" style without becoming tiring. Perhaps is because you combine well the figures in both hands and that makes, many times, a counterpoint effect. Modulations in middle section are good.
This is amazing. The music is much more expressive with the pictures.
And the music itself is the kind of music I like. I see that the number of instruments you choose is the right one. Harmonies are beautiful (and non tonal, I guess), I don't agree with people that always say atonality is only for "terror music". This piece is somber and, perhaps, "dark", but in one sense it's also peaceful 8for me, at least).
This is my largest concertante piece up-to-date, my flute concerto. It is not so virtuoso for the soloist and focuses more on melodic beauty and long expressive lines. Of course it has tricks and fast energetic motion, especially in finale. But the central "heart" of the music is a long second movement with slow, almost like never-ending breath of melodic freedom.
