One such instance is the Seaboard. What first looks like a wonky George Foreman grill turns out to be a musical keyboard. But unlike traditional pianos, all its keys are black and, even more unusual, they are made out of a malleable material. That makes the keys soft and creates a continuous playing surface.
This continuous surface allows a musician to hit a key, then press harder for the sound to become louder. The technology embedded in the keys senses the pressure of your finger, causing a more responsive crescendo. You can start vibrating your finger on a key, like a violist would do on a string and the Seaboard will start making a vibrato sound. What makes the Seaboard so compelling is that these actions, starkly at odds with our understanding of traditional keyboards, feel strangely natural. There is no technical interface to be learned or YouTube video to watch. The materials and technology coalesce in a way that encourages actions that are deeply human.
