I've been meaning to do this for at least a year, no, more than a year. Starting this weekend I've finally started into that project.
Given the sheer length of such a project and the complexity of writing about the first published polyphonic cycle for solo guitar to have been composed by a guitarist I can't realistically try to knock out everything to be said about any paired prelude and fugue in blog posts. That said, I'll try to blog about them in posts where I can pair up discussions of a major key prelude and fugue and a minor key related prelude and fugue. So I'll start with C major and A minor.
Where possible, of course, I'll link to video performances so that you can listen. This will only be possible for a fraction of the entire cycle, however. Since much more of the first half has been made available online it will be easier for those who do not already own the scores for this cycle to read the blog posts where video performances are already available. Where practical I'll try to describe what happens that I find interesting along the way in each of the pieces. But if you don't have the scores yourself there's only so much I can do. Since, however, I am intending to advocate on behalf of this cycle I can at least write something and publish it here at this blog. On account of this blog having a ... history of discussing and presenting information about more controversial topics like the history of a religious movement within the Puget Sound I hope readers who may be new to reading this blog can appreciate why the default position here is all comments are moderated and may not get published. Now that the blog is finally roaming about toward topics that aren't constantly connected to Mars Hill that doesn't mean I've reached some epiphany that insists that people are well-behaved on the internet. :)
So, with that caveat in mind, if you feel inspired to comment about this series of tagged posts discussing Koshkin's contrapuntal cycle you're welcome to comment, even if I can't exactly promise that comments will be moderated or published right away (if at all).
