 Pianos Make Music Accessible Like Computers Make Math Acc...

Though it has become a naturalized part of music-making since the first one was built in 1710, the pianoforte (its name means "soft-loud") was a technical marvel for its time, a machine that changed music in ways that are hard to imagine. Computer pioneer Alan Kay once observed that any technological advance is "technology only for people who are born before it was invented,' and in the case of the piano, this applies to no one alive today. Seymour Papert, the MIT researcher, concluded, "That...

 What if Extraterrestrials Spoke in Music?

Might interstellar communication not be messages but music--perhaps a 600 part invention, each part on an adjacent frequency channel? If there were more conventional representation of frequencies for example, the full frequency range corresponding to the range between 1420 and 1667 megahertz would we have the wit to distinguish this music from noise. Other forms of such many-part interstellar musical inventions might exist which each A civilization provides one part. Might we be able to recog...
