Music Composers Unite!
Overall, I think the 'conversation' aspect was true to form - I think guitar with a woodwind is eminently suitable for this.
Structurally, I yearned for a few things I felt were lacking, mainly, some variations in the guitar inversions - especially the first four minutes or so all felt like they were in the same range, and some work higher up the fretboard would bring some good contrast - and the other was the timing of the clarinet line: I don't think I heard one dotted phrase, or a demi-semi, or an arpeggio or appogiatura, all of which are characteristic of the instrument and add colour and flow to the line without disturbing the mood.
Adrian, you're probably going to be angry with me, but I think the accompaniment you're trying to create here might actually be the harp. This works much better for harp than either piano or guitar, in my opinion. The harp would give you the delicacy you need on those arpeggios. It's a really pretty piece, and has a lot of potential. I know you've now done two versions, but if you have the time, you might consider trying it. I'm positive the result would be worth the effort.
You could do it for Irish Harp, which has no pedals. then all you need to know is the range. It would be much like writing for guitar.
I almost bought an Irish Harp a long time ago, sure wish I had...anyway, you could use any harp sample you have, just keep in mind the range, and pretend it's an Irish harp. the reason I'm "harping" on this is that the piece, at least to me, has a delicate, Debussyish quality that a harp would be perfect for. I've never heard that combo before, but I'm sure the two instruments would get along. And your clarinet melody cries out for it, to my ears. But I know it would be more work. Perhaps you could keep it in mind for some time in the future.
I have made a number of changes, to what I now consider a final version.
The register of the clarinet has been raised in places, and the guitar has a go at the melody in more places.
