This past September, I was in Seattle (to play a show as Blue Sky Black Death’s vocalist). I bumped into my friend David Lu, and over lunch at Elliot Bay bookstore, we took an idea he had and sketched it out on a napkin. The idea was simple: A musical instrument where drawn lines becoming plucked strings, with pitch based on length.
Lots of possibilities. Can you layer loops as you perform, like physical stomp boxes? Can you use two fingers to create a bow? Can you tune your strings to form a particular chord or scale?
I got a quick Flash prototype working during following weekends (shown in video). The plucking physics involved a lot of trigonometry, and fine-tuning things like decreasing the flexibility as you approach the endpoints. The audio samples are cello pizzicato from corscia_s at freesound.org.
