nice! and you can change the feel of the sound by using these bits. sound changes lowering the barriers to creativity can help musicians who struggle with mobility. like yurina, an avid pianist who is connected to a respirator and unable to leave her house, so she is controlling this grand piano at yokohama city hall remotely. it is part of a project between yamaha and tokyo university of the arts. when yurina presses a key, the auto—accompanied piano plays along with her. she practised playing her side slightly ahead of time, as it takes about 100 milliseconds for her piano signal to reach the concert hall. none of these new creativity tools detract from the massive benefits of learning a physical instrument. in fact, i think they complement each other. technology at its best, giving the gift of music to everyone.
