I registered a while ago, but I don't believe I posted anything (well maybe one thing). Well, here I offer up something I worked on years ago now, and I had trouble figuring out where to go with it. Originally I was following some suggestions from Musical Composition by Smith Brindle on building melodies, but I may have made the mistake of harmonising too early.
I suppose the other question is, does it sound like it wants to be a small piece or something more extended?
Rather than attach a file, I've got a link to bandcamp already as I was trying it out: http://arpa.bandcamp.com/ - I call the thing "Eastern Mystery" because it sounds vaguely oriental.
This seemed like a good place for some more detailed feedback - at the moment I don't have a lot of technical commentary on how my ideas can be developed, although I do have a very good selection of books to help.
