As a musician who has studied of all forms of acoustic and electric keyboard instruments, I have played the gamut of keyboards, from gems to disasters. I think the most significant keyboard developments of the 20th century were the Hammond organ, the Fender Rhodes electric piano, and the Moog synthesizer. These instruments were notable not for their ability to replicate the sound of acoustic instruments, but for the new timbres and textures possible with them, which have since become permanent parts of our musical vocabulary. I have now played an instrument that may prove one of the most significant keyboard designs of the 21st century: the Yamaha AvantGrand N3.
