I came up with this riff near the end of class today and wanted to post it so that I (or others) might run away with it and add lyrics or expand it out to a fuller song. The main bass note is F# throughout, with some noodling on the D / G strings; I threw in some Bmaj / Amaj chords at various points as well.

If you so choose, adding to the riff will garner you half of these stars as well. Go nuts!
