I got my copy of Carl Wood's "Saxon Songs" a while ago. I've read the text and picked out a few melodies, but I'm calling this a "pseudo-review" because I haven't actually yet played any of the full arrangements.
She comes right out and says in her Introduction that this is not an attempt at historical re-creation. It's a modern composition. This is rather at odds with the ad copy, and I admit I was disappointed. The other supporting information is the usual; no sources I was surprised to see. She does give a handy pronunciation guide for Old English.
The music looks very "harpistic," lots of rolled triads or four-note octaves. It does look to be in either minor keys or else modes - it's hard to tell at first look, and from the chordal tablature, if it's "really" a minor key or if that's the modern analogue to the mode. (For instance, the key of D-minor is not the same as D-Dorian, but a D-minor I chord and a D-Dorian I chord are the same. The note in the scales that is different doesn't show up in the chord.)
The melodies have some accidentals dropped in; I don't like the effect right away, but maybe it grows on you? My very brief acquaintance with Icelandic folk music showed that it had some accidentals, and maybe that's where this is coming from. That, or Wood's imagination and art.
It is a good example of through-composed settings for Anglo-Saxon poetry.
On the whole, I'm not unhappy that I bought it, and I hope to be able to try a few of the pieces soon. However, I'm not as excited about it as I was before learning it was an entirely modern take on things.
