Plurry: a scheme for a musical instrument
Description (with about 60 diagrams) of a suggested instrument,
"the contemplation of which can reveal and clarify much about
the mathematical basis of music." The distinguishing idea is
not in the material or mechanism (it could be realized as a string,
percussion, or wind instrument or as a keyboard) but in the arrangement
of the tones in a network of two dimensions (roughly: octaves and
fifths). This leads to an extraordinary wealth of enlightenment
on the diatonic scale, keys and modes, the tempered scale, and much
more. The instrument itself could open new worlds of sound. Anyone
is welcome to try to build it!
