FORWARDED: Curved Keyboard (Modified by Kent Swafford)

[Stéphane Collin]

Well,

It could be a silent keyboard, like those that regarding pianists take with
them on tour, for practicing scales and arpeggios without disturbing their
wives.  Twice more octaves would mean twice less bottom to top runs for same
fingerwork.  Seems ideal for people twice quicker bored by technical
exercise.

(Hope you do fine, Conrad.)
