This week's flash composition turns out to be the first woodwind quintet in the series. Without the 10-minute time limit, I would have developed the section beginning at measure five further. Still, I was surprised at just how far this sketch got before time ran out.
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.
