So, here are some random riffs of mine, both for the guitar and ukulele, so far unconnected to any larger piece of music.
A Little Mischief
I've since added a little more to "Bleak," but I don't have a midi of that draft to post.
Many of my riffs and songs began when I put my fingers over random frets and seeing what kind of chord it made. I thought this one had a nice East Asian flavor. I play this one as close to the bridge as possible to get that tinny sound.
The title of the next one is obviously a play on "Dust in the Wind," from which I got the picking pattern.
Lint in the Breeze
Here's another little riff that began as a random chord that I liked.
This last one is an ukulele riff. The title is a combination of Flea, the model of ukulele I play, and blue, since this is played in a blues scale.
That's it for now. Most of my subsequent updates will probably be single riffs like this, since they're easier to come up with than complete songs.
