Firstly, I would like to mention that the Arpeggione sonata is soooo beautiful! I've played it on viola (with a pianist!) and it is oodles of fun! Also playable on cello, but doesn't sound as good! ;-) (I'm biased though)
This is one of my absolute FAVOURITE techniques because it is fast, totally unpredictable, and very in-the-moment. To do this kind of picture this is the procedure that you would need to follow:
1. Prepare your art supplies so they are within arm's reach the very moment you will want them. These include: ink, water, possibly watercolours if you wish, a paintbrush (large), a quil, and glossy paper!
2. Put on a beautiful classical/operatic tune and get started! The rule is that you must start and stop with the music!
3. Splash water on the paper and then use either the quil or the brush with ink (or watercolour) - it will look very cool as it expand in the water and goes thin and delicate in the dry areas
3. Experiment! Twirl the paper around (drip technique!), spatter water on the ink (this creates cool effects!), spatter ink on, etc. Go with the music!
4. Add dark accents (the picture dries very fast so you will not have to wait)
5. Let it dry if there are any dark wells in the art - do not soak them up!
So there it is! In this picture, I actually got a very interesting result because I used very old ink and it was in clumps (the last close-up shows these) - all for the better! Use these strokes of luck to your advantage!
