This week's 10-minute sketch is a short piano piece. I wrote out the bass line first to serve as a ground. I then added the melody and filled in the harmony last. If I were to continue this sketch, I'd probably make it a stand-alone composition. Like the Renaissance keyboard fantasies that I modeled it after, I'd keep increasing the complexity of the music above the ground with each iteration.
As always, you can use any or all of the posted Diabelli Project sketches as you wish for free. Just be sure to share the results. I'm always curious to see what direction someone else can take this material.
